Quantum Teleportation: Paving the Way for a Quantum Internet
August 16, 2019 August 16, 2019 By Gabriella Skoff	1 Comment
Last week's big quantum news centred on two proof of concept studies, both of which claim to have achieved quantum teleportation using a tripartite unit of quantum information called a qutrit, for the first time. While quantum teleportation has been demonstrated previously, it has only been carried out with qubits, which are capable of storing less information than qutrits but thought to be more stable. The novel feat was achieved independently by two teams, one led by Chinese physicist Guang-Can Guo at the University of Science and Technology of China (USTC) and the other, an international collaboration headed by Anton Zeilinger of the Austrian Academy of Sciences and Jian-Wei Pan of USTC. While both teams have reported their results in preprint articles, the article by the Austrian-led team has been accepted for publication in Physical Review Letters.
Competition for credit of this achievement aside, the team's findings ultimately support each other in substantiating an advancement in quantum teleportation theory: namely, that quantum networks should be capable of carrying far more information with less interference than previously thought. This advancement—like many in the world of quantum—is likely to be found most exciting for physicists, evading the grasp of an applied significance for those of us with less scientific minds. Nevertheless, the notion of quantum teleportation has once again grabbed headlines and imaginations, providing a good opportunity to explore the concept and the applied significance that advancements like this might eventually have on our world.
While it may sound flash, quantum teleportation is an affair less akin to science fiction than one might imagine. On a basic level, quantum teleportation differs from 'Star Trek teleportation' because it is used to transmit information rather than macroscale physical objects, like human beings. This is possible because of quantum entanglement, a phenomenon of quantum physics that allows us to look at one particle or group of particles and know things about another, even if those particles are separated by vast distances. Quantum teleportation relies on entanglement to transfer information based on this shared state of being demonstrated by entangled particles. As such, quantum teleportation can be defined as "the instantaneous transfer of a state between particles separated by a long distance".
Quantum teleportation holds the most obvious promise in the discipline of quantum communication, where its impact in secure communication was established as early as 1997. In 2017, Chinese scientists working with a team in Austria made waves with their announcement that they had achieved transnational quantum teleportation, establishing a quantum-secure connection for a video conference between the Chinese Academy of Sciences in Beijing and the Austrian Academy of Sciences in Vienna, some 7,600 kilometres away from each other. The experiment utilized China's Micius satellite to transmit information securely using photons. Micius is a highly sensitive photon receiver, capable of detecting the quantum states of single photons fired from the ground. These photons, beamed via Micius, acted as qubits, allowing researchers in both countries to access a shared quantum key and thus enabling them to participate in the quantum-encrypted video call. Critically, should the data have been accessed by a third party, the code would be scrambled, leaving evidence of tampering for researchers at both ends of the connection.
This experiment, facilitated by quantum teleportation, proved two fundamental and impactful theories in quantum physics: that quantum communication can provide a previously unfathomable level of security and that it is capable of doing so on a global scale. Given these capabilities and coupled with the new qutrit proof-of-concept work, the realm of applied possibilities for quantum teleportation is expanding.
Aside from ultra-secure, transcontinental video conferences, one very hyped application for quantum teleportation is in the development of a hyper-fast quantum internet. Due to the entangled state of particles, information is transmitted instantaneously in quantum teleportation—faster than the speed of light. However, the transfer of this information is still required to operate within the current confines of classical communication. As such, even quantum information must travel through ground-based fibre optic cables or via photon-sensitive space-based satellites, like China's Micius. This infrastructure is both expensive and potentially expansive, posing a formidable challenge for a global roll-out of a quantum internet. Still, these early experiments have laid the groundwork for the development of a quantum-secure Wi-Fi by putting theory to the test and producing promising results.
Currently, a team of researchers at Delft University in the Netherlands is working to build a quantum network, using quantum teleportation as the mode of transport for information between linkage points. The project, which aims to connect four cities in the Netherlands, is scheduled for completion in 2020. In China too, researchers are constructing the backbone for a quantum network to connect Beijing and Shanghai. Aside from the support of private corporations such as banks and other commercial entities, progress on the concept of both localised and international quantum networks has been spurned by pressing anxiety about global levels of cybersecurity
A critical advantage to a future quantum internet is the enhanced security afforded by quantum teleportation—the ability to create an unhackable connection. This could have serious implications for national security and could present a potential solution for many foreign surveillance and interference challenges that countries face today. For example, it is now public knowledge in the U.S. that Russia has the demonstrative ability to directly interfere with most paperless voting systems. While states are currently reticent about making changes to the current U.S. vote-casting system, alternatives are slowly being considered—from regressive paper ballot casting to progressive blockchain applications—in order to safeguard American votes against hacking efforts. Quantum teleportation could offer an interesting alternative in this space as the technology continues to develop.
Though quantum teleportation will not be transporting human beings between planets any time soon, it will play a key role in ushering in an internet revolution. While it remains to be seen exactly how that revolution will play out, it is clear that it will bring an unprecedented level of security and speed to global communications. It is also apparent that the level of interest in the secure and high-speed communications afforded through quantum teleportation is broad and deep, spanning both public and private sectors across the globe. Quantum teleportation has recently seen a number of experimental proofs, pushing the field of quantum communications to the fore of quantum development and promising to deliver a much sought-after security transformation within the decade.
Andrew Yang 2020: Growing American Faith in Techno-Realism

The U.S. 2020 Democratic Primary is well underway, exhibiting the greatest diversity and highest number of Democratic candidates in U.S. history. From career politicians to a self-help guru to a former tech executive and everything in between—this extraordinary breadth makes for an interesting array of policy positions, on topics both expected and fringe. While technological innovation, economic growth and security have all become inextricably linked to American politics in general, the Democratic Party in particular has worked to frame itself as the harbinger of technological innovation since at least the Kennedy years. This year, Democrats and Republicans have moved closer together on technology as regulating Big Tech has become a salient challenge in government. Many Democrats in this year's Primary are also heralding the manufacture and export of green technology as part of their solution to climate change and domestic unemployment. But one candidate in America's 2020 Democratic line-up is talking about innovation and technology in a very serious way: Andrew Yang.
Andrew Yang is a former tech entrepreneur most well-known as a champion for a Universal Basic Income (UBI) through his flagship proposal, the Freedom Dividend. He frames his argument for the implementation of a UBI with the encroaching threat of mass job loss, as automation continues to permeate high-employment sectors like retail and the foodservice industry. With close to no political experience on his resume, nearly all of Yang's policies rely on his knack for Silicon Valley hype and focus on the promises and threats of technology. His "human-centred capitalism" platform boasts a number of compelling and futurist tech-forward solutions, including what he refers to as the "new currency" called Digital Social Credit, which would see the creation of positive social value transformed into financial capital for the individual. Though many of Yang's ideas may sound like sci-fi realities, he seems to view technology more reasonably as a useful tool to be harnessed in America's path forward, making his message fall short of techno-utopianism and settle more comfortably into techno-realism.
Unsurprisingly, Yang is the only Democratic candidate to make specific mention of a quantum policy, which centres around two neat "steps", according to Yang's 2020 candidacy website:
First, and immediately, we need to invest in and develop new encryption standards and systems, and immediately shift to using these quantum computing-resistant standards to protect our most sensitive data. This won't be easy or cheap, but it is necessary. Second, we must heavily invest in quantum computing technology so that we develop our own systems ahead of our geopolitical rivals.
While Yang's quantum policy has been criticized by some for being simplistic or simply an activation of a buzzword frenzy, he remains the only candidate to have one. His policy is palatably outlined as a two-step program on his website but importantly seems to suggest Yang's commitment to government investment in quantum technologies in order to increase both defensive and offensive U.S. quantum capacities. This stance clearly signifies Yang's opinion that having an advantage over the rest of the world in quantum technology is a strategy that will be integral to the maintenance of American hegemony. Further, his position on foreign policy, which he characterizes as one of "restraint and judgement", is well-suited to a quantum-enhanced security capacity that, in a modern show of military might, could demonstrate U.S. technological superiority to attack and defend without putting boots on the ground.
In these still early days of the race for Democratic candidacy, Yang's and most other's policies lack the proper framing and focus that will be required to get the public onside. While Yang may be wearing rose-coloured glasses when he emphasizes the power of technology to solve social ills, this angle has made him stand out from an array of incredibly diverse Democratic candidates. His current popularity ratings place him in the top ten candidates, above even well-known career politicians like Cory Booker, who have had much louder voices thus far in the Democratic debates. It is clear that there is something about Yang's message that resonates with Americans. Though his press-time has been minimal, he has achieved some obvious success in delivering his message about the promises and perils of emerging technologies and how to harness and minimize these.
It is unlikely that Yang's tech-forward platform will be enough to win him the nomination but the fact that it has already taken him this far should tell us something. Like most populations throughout history, Americans are concerned about the influence and the impact that emerging technologies are having on their daily lives and will continue to have on their futures. Americans seem to be interested in Yang because they want someone at the helm who has the prescience to control and channel these technologies in their best interest. At least in the U.S., however, running on a political platform focused almost exclusively on emerging technologies poses two major challenges: framing and a far-reaching, futurist vision.
First, a political message framed by tech-forward policy needs to be delivered in an accessible and pressing way. Yang's framing of job loss due to automation is, in fact, an example of how this can be done effectively. Unemployment is a very real issue to both Democrats and Republicans and Yang's message activates and engages both of these parties while framing the issue in terms of emerging technology. Second, in order to harness the power of tomorrow's technology (quantum computing, for example), one needs to have sights set on the future. And not just the near future, but a future that is well beyond the purview of one presidential term of four years, or even two of eight years. This requires a bold vision that can border on futurist and risks the argument of the unknown. How can emerging technologies be channelled/regulated if we don't even really know what they will do? The reality is that most politicians speaking about technology are either unable to grasp and communicate the topic of emerging technologies or not looking far enough into the future to really be able to create proactive policy in this area.
It is perhaps the most formidable challenge in politics, getting the general population to care about far-sighted goals, and one that has rarely been achieved outside of the force of dictatorships, whether benevolent or not. Generally, most communities (bar Silicon Valley) are not going to be receptive to the message of a platform built solely around emerging technology. In contrast, most people are concerned with matters they can relate to and issues that seem far more pressing, such as employment, infrastructure or education. Technology, of course, is increasingly an imposing factor in the conversation on these and most other topics of political debate, but it is often an intangible factor that requires a certain amount of faith. Like Church and State, Technology has become inextricably and implicitly intertwined with politics. Some, like Yang, speak about it with as much fervour and conviction. A candidate with a strong ethos of technological innovation and regulation certainly has the best chance of creating a government centred on these values. This begs the questions—is mixing technology and politics a good thing? Or, perhaps a more realistic question, like the relationship between Church and State, is it even avoidable?
Quantum International Relations
Where is the Middle East in the Quantum Race?
July 26, 2019 July 26, 2019 By Project Q	No Comments
The quantum race, like the space race before it, is a technological marathon with major implications for international relations. This defining quality sets the stage upon which the race is run, presenting competitors with an opportunity to demonstrate their economic and technological prowess to the rest of the world. Perhaps even more so than in the case of the space race, the winner of the quantum race will establish the winner's name as a world leader in the Digital Age by gaining an unparalleled, strategic security advantage. With such high stakes, countries across the globe are investing in building their quantum capacities, if not to win the race, then at least to not be left behind. While China and the U.S. are currently frontrunners, countries from Europe to Latin America are joining the race, rapidly investing in quantum technology research and development. And yet, a region that has for so long dominated discussions about international relations and security appears to be missing in the line-up. Where is the Middle East in the quantum race?
For most nations in the Middle East, quantum investment is simply not a major priority. There is a complex set of reasons, unique to each country, for why this is the case. Many countries in the region have been plagued by war and instability over the last decade—producing both a deficit of government funds and an inadequate environment for exploration and innovation to occur. As with the space race, the countries that have risen to the top of the quantum food chain have done so upon the backdrop of relative stability, growth and wealth. Several countries in the region, however, have begun to emerge as quantum competitors with increasing capacity and focus: Israel, the Gulf countries, led by the United Arab Emirates (UAE) and the Islamic Republic of Iran.
These countries share some of the conditions required for the establishment of international technological partnerships, investment and a privileged focus on innovation. The ambitions and specialities of their growing quantum programs, however, differ notably in relation to their specific geopolitical situations. Israel, a country known for its heavily U.S.-funded defence and arms expertise, is investing in quantum technologies largely for security applications. The Gulf counties, well-known for their economic reliance on oil production, are distinctly invested in the areas of innovation and capacity-building, especially in the UAE where there is a growing focus on quantum applications in the energy industry. Iran's quantum efforts, largely directed through well-established and internationally connected knowledge institutions, are also heavily influenced by the Joint Comprehensive Plan of Action (JCPOA, commonly known as the Iran nuclear deal).
While scant information is available about these countries' nascent quantum efforts, their momentum is growing, slowly but surely. From a geopolitical perspective, the ability to compete on the global stage with quantum technology research and development would be a critical advantage for any nation in the Middle East.
The quantum race began in earnest in the early 2000's, making Israel a late-comer to the game. Just last year, Israel's Prime Minister, Benjamin Netanyahu, announced the country's entrance into the quantum race with an investment of NIS 100 million in a quantum technology research fund (approximately USD 28.2 million equivalent). According to The Jerusalem Post, the ongoing project is a collaboration between the Defense Ministry's Administration for the Development of Weapons and Technological Infrastructure (MAFAT), the Higher Education Committee and the Israel Science Foundation. The project's aim is to support Israel's intelligence-gathering capacity, and as such will likely focus on the areas of quantum communications and computing. This month, Israel's Ben-Gurion University of the Negev (BGU) announced plans to pursue joint quantum research and development programs with the Israel Defense Force (IDF) and U.S. Defense Forces, along with other high-tech industry players both in Israel and abroad.
Significantly, Israel is the largest cumulative recipient of U.S. foreign aid since World War II and the vast majority of this funding, quoted at $134.7 billion total, goes directly to Israel's defense programs. As such, Israel's ability to support scientific research and development (R&D) with military funding has come to resemble the American system, where the Department of Defense (DoD) is one of the biggest funders of national scientific research and development. This has manifested as vast amounts of military investment in Israel's high-technology sector. According to the OECD, the country's gross domestic spending on R&D since 2015 has been the highest in the world. As a result, the science and technology sector in Israel is one of the most well-developed and profitable in the world.
Historically, Israel has prioritised the development of home-grown technological expertise and innovation through industry and its higher education system. The immense amount of military and defense funding coupled with highly-skilled immigration booms and an extremely economically and socially invested network of Jewish populations living abroad have enabled Israel to build a thriving, national high-technology industry. Geographically surrounded by Muslim-majority countries in a radically contentious area, Israel has maintained its space in the Middle East essentially through establishing its presence as a highly militarized nation with vital support from powerful friends. Within this context and motivated by a lack of natural resources, Israel became the leader in high technology military exports that it is today.
Given this context and history, Israel's recent pivot in focus toward quantum technologies is no surprise. The country's keen focus on security and defense applications currently dominates the scope of their quantum R&D programs, but civilian applications are promised as the next phase of development.
THE GULF NATIONS
While Israel may eventually corner the market in quantum computing and communications for military applications, the Gulf nations of Saudi Arabia, Qatar and the UAE have entered the race with a different aim. This year the Gulf nations launched quantum computing research groups in their respective countries with the goal of creating an ecosystem for capacity-building and ultimately, knowledge production, in quantum technologies. Already an authority in technological research in the Middle East and a rising star in research output worldwide, Saudi Arabia's King Abdullah University of Science is well-positioned to become a regional leader in the quantum computing space. Further, Saudi Arabia's Aramco presents existing experience with supercomputer systems, a considerable advantage in the quantum race.
Recently, the UAE has turned its focus toward forming vital partnerships with global tech giants and has been rewarded by agreements with some of the biggest names in quantum computing, D-Wave and Microsoft. Last year, the Dubai Electricity and Water Authority (DEWA) announced its participation in the Microsoft Quantum Computing Programme to develop quantum-based solutions for energy-optimization. Notably, DEWA is the first organisation outside of the U.S. to participate in the program. This suggests the UAE is taking a forward-looking approach to shift its economy and applying quantum innovation in the sustainable energy sector—a strategic pivot for a country where 30% of the GDP is directly based on oil and gas output. Last year as well, the UAE Minister for artificial intelligence enacted a partnership with Canadian quantum computing company, D-Wave, to bring the region its first quantum computer, which will be housed at the Museum of the Future in Dubai.
Broadly, these advancements are couched by the motive to ensure the ongoing production of innovation through knowledge development, a trend that is currently sweeping the Arab states. The pressing need to begin diversifying the economies of these oil-producing nations has also contributed to investment in new quantum programs. However, the Gulf countries lack the population sizes and national research budgets to compete with the rest of the world in the quantum race. For this reason, the Gulf countries are looking toward public-private partnerships as a way to develop their quantum computing sectors further, bringing vital knowledge and facilities to the region.
These recent developments appear to be at least in part a response to a widely-referenced 2019 World Government Summit report authored in partnership with PricewaterhouseCoopers (PwC) by Simone Vernacchia. The report seems to have stoked a fire, urging the Gulf countries to begin investing in quantum technologies:
If they do not, they risk missing out on the many advantages that will be on offer across every sector, and they will face an increasing threat if they fail to plan for the next generation of cyber-security…. Building up knowledge and specific skills in the field, along with preparing defensive post-quantum computing cyber-strategies, can be considered urgent priorities.
The report makes clear the risks of missing the moment to join the quantum race but also points to a number of regional opportunities for quantum innovation within the existing oil production industry, national security apparatus and diversification into new industries. It is clear from the establishment of these early partnerships between the UAE, D-Wave and Microsoft, that the report's warnings are not being taken lightly. Rather, the advice is being heeded as essential to ensuring the supremacy of the region's economy and continued security.
A regional competitor to the UAE, Iran is also vying for a place in the quantum race and hoping to take the lead in quantum technological facilities and know-how in the Middle East. The country has had sights set on quantum research as a game-changing industry since around 2015 with the signing of the JCPOA. The JCPOA deal stipulates that in exchange for Iran limiting its uranium-enrichment activities, sanctions against the country imposed by six of the world's biggest powers will be lifted. The agreement also opened a door for Iran to collaborate with Euratom, the European atomic energy community working in high technology development for nuclear power. Given the tumultuous U.S. withdrawal from JCPOA, Iran's recent quantum efforts have focused on collaboration with European countries and the continued development of its own national capacities.
Although several sources from 2017 state that Iran has entered talks with European nations to collaborate on quantum technology it is unclear whether or not any agreements have been actualised. The Atomic Energy Organisation of Iran (AEOI) appears to be the main authority involved in negotiations to build the country's quantum industry. While European collaboration is a nebulous topic, it appears that the AEOI has been busy at work, proclaiming the two recent victories of creating Iran's first laboratory equipped with quantum technology research facilities and running its first photon entanglement experiment.
Iran also boasts some of the most well-developed quantum information science programs in the region. As such, the quantum literacy of Iran's scientists and engineers is higher than in many countries that lack such long-standing research specialisations. The Islamic Republic's two leading quantum research groups, the Sharif University quantum information group and the Quantronics Lab at the Iran University of Science & Technology are internationally renowned and well-equipped. These advantages were achieved either despite international sanctions, or in the more likely case, after they were lifted through the JCPOA. Last year, the first National Conference on Quantum Technology was held in Tehran and the International Iran Conference on Quantum Information, led by the Sharif group, is now in its sixth year. These conferences serve to bring international knowledge of the latest quantum developments to the region, helping to put Iran on the map as a contender in the quantum race.
It is still early days for the Middle East in the quantum race. The growing quantum programs in the Gulf nations, Israel, and Iran have only been formally created within the past three years and as such their outputs and impacts remain minimal. Nevertheless, these countries, which have been lucky enough to prosper in relatively stable economic and political circumstances, have seized the valuable opportunity to participate in and even to help build what is promised as the next technological revolution. While only time can tell exactly how the quantum race will pan out, this regional competition will undoubtedly open up possibilities to shift existing power dynamics not just between these quantum-empowered Middle Eastern countries, but also on an international scale.
Could Quantum Computing Help Curb AI's Carbon Footprint?

For the first time, the environmental impact of training AI in natural language processing (NLP) has been quantified, and the results are jarring. The lifecycle of training an NLP deep learning algorithm has been calculated in a new paper to produce the equivalent of 626,000 pounds of carbon dioxide—nearly five times as much as the lifetime emissions of the average American car, including the manufacturing process. The paper brings new life to a parallel aptly drawn by Karen Ho in her article on the research for the MIT Technology Review: The comparison of data to oil now extends beyond its value in today's society to also encompass the massive costs it weighs on the natural environment as an industry practice. The team of researchers found that the highest scoring deep learning models for NLP tasks were the most "computationally-hungry"; far more energy is demanded to train them due to their voracious appetite for data, the essential resource needed to create better AI. Data crunching is a space in which quantum computing is expected to lend a critical advantage to deep learning. Could it also help to curb AI's carbon footprint?
The environmental impact of data is not often discussed, due in part to its lack of visibility. Fossil fuel plants can dominate the skyline, the plumes of smoke billowing above them have come to symbolise a problematic issue for many. Documentaries have taught many of us that even cows have a surprisingly large impact on climate change due to their production of methane gas. Data centres, however, are far less ubiquitous polluters, though their impact is substantial. The global ICT system is estimated to require about 1,500 terawatt-hours of power per year. To put that into context, that's about 10% of the world's total electricity generation. Given that the majority of the world's energy is still produced by fossil fuels, the biggest contributor to climate change, this represents a serious challenge that few seem to be talking about.
As computers become more powerful, their power-usage too increases. Supercomputers are known to be incredibly gluttonous when it comes to energy consumption. In 2013, China's Tianhe-2, a supercomputer with a generating capacity of 33.9 petaflops, was one of the most energy-intensive computers in the world, using 17.8 megawatts of power. Tianhe-2's electricity consumption is about the same amount of energy required to power an entire town of around 36,000 people. While supercomputers today are used for anything from climate modelling to designing new nuclear weapons, many of the next generation of supercomputers are being tailor-made to train AI.
The U.S. Department of Energy Oak Ridge National Laboratory's (ORNL) Summit supercomputer is the first supercomputer to be specifically built for AI applications. Summit is capable at peak performance of 200 petaflops, establishing the U.S.'s ascent to top-player in the supercomputing world, a place only recently taken from China. The U.S. aims to reach the next milestone, building a supercomputer capable of an exaflop (a billion billion calculations per second) by 2023. The numbers speak for themselves. A future reliance on these supercomputers to train AI will result in exponentially greater energy usage, by a factor that in today's stubbornly reliant fossil fuel society would have a severely negative impact on climate change. While there are some looking toward other power alternatives for training AI, perhaps quantum computers, which require far less power than supercomputers, could support a more energy-efficient transition for AI training.
Currently, quantum computers still use more power than classical computers because of their extreme cooling requirements. Most quantum computers use cryogenic refrigerators to operate, which are immensely energy-inefficient. As such, the vast majority of a quantum computer's energy usage is pulled directly to the cooling infrastructure required in order to operate it. However, the advantage of this refrigeration technique is critical in quantum computing: Operating at temperatures near absolute zero enables quantum processing to be superconducting. This allows them to process information using almost no power and generating almost no heat, resulting in an energy requirement of only a fraction of that of a classical computer. According to the ONLR, "quantum computers could reduce energy usage by more than 20 orders of magnitude to conventional [super]computers".
Quantum is expected to lend an essential boost to AI and could be used for more effective training in deep learning tasks such as NLP in the future. While the operating costs on the environment of quantum computers may be high due to their cooling requirements, novel cooling techniques are being explored, which could one-day present potential solutions for quantum's power problem. As the AI industry continues to grow exponentially, it is imperative that its environmental impact be considered in order to direct a more responsible development of the sector. Even with the high level of operational energy usage factored in, quantum computers present a distinct energy efficient advantage over supercomputers and could be used to help curb the carbon footprint of training tomorrow's AI.

Saving Schrödinger's Cat: Researchers Discover an Early Warning Signal for Quantum Jumps
Feature image via Science X.
Schrödinger's cat is a thought experiment that has become well known as a symbol for the "weirdness" and unpredictability of the phenomenon of quantum superposition. The eponymous thought experiment devised by Austrian physicist Erwin Schrödinger in 1935 involves a cat, a vial of poison, a radioactive substance and a sealed box. The experiment dictates that if an atom of the radioactive substance decays then it will trigger the release of the poison, killing the cat; however, that may or may not happen. One can only find out if this has occurred, and therefore if the cat is alive or dead, by opening the box to observe the state of being of the cat. According to the Copenhagen Interpretation of quantum physics, until the observer peeks inside the box, the cat is actually both dead and alive. It is only when the state of the cat is observed, therefore, that the quantum superposition collapses into one or the other states and the cat is found to be either dead or alive.
Based on Niels Bohr's 1913 proposal of quantum jumps, it was thought that the process of the cat collapsing into a theoretically dead or alive state upon observation was both instantaneous and unpredictable. However, new experimental research performed by a team of Yale researchers and published last week in Nature journal, suggests otherwise. Dr Zlatko Minev and his team's findings conclude that a quantum jump does not actually exhibit the random, abruptness that defines the fate of Schrödinger's cat. Rather, their research suggests, "the evolution of each [quantum] jump is continuous, coherent and deterministic".
Within the context of Schrödinger's cat paradox, these findings imply that the continued-life/death of the cat is simply the final stage of a process rather than an instant occurrence without foreshadowing. Further, the Yale team has detected "an advance warning signal" which indicates that a jump is about to occur. This seems to signify that we can not only detect when a quantum jump will occur but that we can also potentially reverse it during the transition. These new findings not only impact our theoretical ability to potentially save Schrödinger's cat from its proverbial death but also have a fundamental impact in applied quantum computing.
The conundrum of a quantum jump has long presented a challenge in the applied field of quantum computing, where a jump in qubits manifest as an error in calculations. Researchers are hopeful that these new findings could potentially facilitate major advances in understanding and controlling quantum information. They anticipate that this new discovery will help to develop an early warning system that can predict when a jump, and therefore a computational error, is about to occur in order to catch it before it happens and reverse its course. While it would be a wonderful conclusion that Schrödinger's dear cat could be saved, the real value of this research lies in its applied context: the potential to develop an advanced monitoring, detection and correction function for quantum systems, which could help bring us one step closer to a quantum advantage.
Grand Theories & Wendt's World
June 7, 2019 June 7, 2019 By Project Q	No Comments
Feature image via Project Q. Alexander Wendt is a "walking, talking waveform function. And so are you!"
Quantum mechanics is an unwieldy field to wrap the mind around, to say the least. Quantum phenomena are regularly referred to in headlines as "weird", even notoriously dubbed as "spooky" by Einstein himself. It is no wonder, then, that the effort to apply quantum theory to the social sciences can often lead to murky associations lacking in lucidity. Yet the divide between the hard sciences and the soft sciences is also blurry. After all, do social phenomena not take place in a world that is ultimately physical? With great clarity and simplicity rarely found in the world of quantum, Grand Theories, a new podcast series that "explores lesser-known ideas that try to explain really big things about the world we live in", dives into the world of the quantum social sciences.
The podcast's second episode entitled Quantum Social Sciences and A Holographic Society investigates the recent work of political scientist Alexander Wendt, unpacking some of the complexities and implications of what the podcast calls "Wendt's Quantum Society". In this episode, Grand Theories creator and narrator Mark argues to Wendt's point that perhaps quantum physics can provide a better framework for understanding our social world than classical physics can. This is due in part, he argues, to quantum's ability to account for randomness and subjectivity. No one would argue that human life is characterized exclusively by the type of cold, hard rationality that is a hallmark feature of dominant economics and international relations thinking like utility maximization and game theory.
Mark explores Wendt's ideas on quantum social theory by first elucidating some tricky quantum physical theories that underpin Wendt's 2015 book, Quantum mind and social science: unifying physical and social ontology. He tackles concepts like Heisenberg's uncertainty principle, the observers effect and entanglement with great clarity, employing a refreshingly accessible tone for non-expert audiences. Through Mark's analysis of these quantum theories, it becomes clear where Wendt draws parallels in order to interpret our social world through quantum physics. Mark refers to "Wendt's World" as "…an undetermined, probabilistic place with a thick sense of interconnectedness". This characterization reflects across Wendt's quantum-social theories discussed in the podcast, including human decision making, consciousness, entanglement, and perhaps Wendt's most bizarre-sounding conceptualisation, that society is a hologram which physically exists in the minds of the people that make it up.
This blending of the physical and the social, as theorized by Wendt, is unique and rarely expounded upon in mainstream social science. Yet, the way in which Mark explores these ideas in his podcast shines light upon not just the potential applicability of this merger but also on the important implications that an understanding of a quantum social world might have. While Wendt's work does not explicitly include a call to action, Mark takes his interpretation one step further to argue that ultimately, Wendt's theories imply that by virtue of being a part of society we have the power to change the things that we are not happy with. This interpretation of a world ruled by both emotions and rationality, empathy and conflict, suggests that human beings are not only capable of collaboration, but actually inherently drawn toward it. Perhaps there is potentiality for an understanding of our social world through this frame to impact social challenges from climate change action to the de-escalation of wars, should we choose to use "Wendt's World" as our dominant global lens.

The quantum race has thus far been dominated by names you have probably heard of: Microsoft, Intel, Google, Rigetti and IBM. A newcomer to the game, Honeywell International Inc., is a company perhaps better known for the manufacturing of aircraft engines than quantum computers. Rather surreptitiously, however, Honeywell has been hard at work developing what is known as trapped-ion computing technology for at least five years now. Unlike some of the other quantum computing contenders, Honeywell stayed more or less out of the quantum headlines until March, when the company officially entered the quantum playing field with a series of announcements on the development of its quantum capabilities. The strategic addition of quantum computing to Honeywell's portfolio is the result of CEO Darius Adamczyk's background in computer engineering and a forward-looking approach, which values the quantum computing sector as a worthy investment for the future of the business.
Adamczyk has expressed confidence in the progressive development of a Honeywell quantum computer, stating that he expects it to begin generating revenue as early as the end of this year. According to their website, Honeywell's quantum efforts have resulted in their ion-trap technology demonstrating "record-breaking high fidelity quantum operations" of 99.997 percent, placing it in the lead just ahead of its main trapped ion competitor, IonQ, which boasts 99.97 single-qubit fidelities. These numbers appear to be promising, but Honeywell cannot yet claim superiority until it is able to report results for two-qubit fidelity, a better measurement of the technology's accuracy over time. Still, these impressive results do place Honeywell as a top contender, directly in competition with IonQ, the only other quantum computing entrant to employ an ion trapping approach.
So, how did a company like Honeywell suddenly become such a major contender in the quantum race? According to Next Platform, Honeywell's quantum journey actually began in 2014, as a participant in an Intelligence Advanced Research Projects Activity (IARPA) program on trapped ion research. With this early experimental work under Honeywell's belt, the company continued to build on its experience in this domain. Further, Honeywell's existing areas of expertise in vacuum systems, lasers and optics and microelectronics fabrication, among other fields, galvanized its ability to become a well-placed contender in trapped ion quantum computing. Simply put by the company's President of Quantum Solutions, Tim Uttley, who leads a team of 100 physicists, engineers and technicians at Honeywell: "If you put all those things together, you can build a quantum computer".
But what exactly is trapped ion quantum computing, and what does this mean in the context of the quantum race? Ion trap is only one of half a dozen diverse quantum computing approaches, including the more well-known superconducting, as well as neutral atom, annealing, silicon spin, topological and photonics. Apart from these approaches to quantum computing being so different, and therefore extremely difficult to compare, is still early days to say which will become the dominant method that will lead to quantum superiority. The ion trap approach, which manipulates charged atoms using lasers in a vacuum, is known for its capacity to reduce noisy interference—a main source of error formation in quantum computing. This approach is thus promising due to its potential to help mitigate the prevalence of one of quantum's biggest challenges. Honeywell and IonQ, a company backed by Google's parent company, Alphabet, are so far the only real competitors to use this technology.
Honeywell's trapped ion technology could give the more mature superconducting approach a run for its money and present an alternative for solid-state quantum computing. Likewise, the company's proven track record with control-system hardware could certainly give it an advantage over the more specialised IonQ. While it is simply too early to tell if these potentially advantageous factors will play a role in Honeywell's quantum success, this new entrant to the world of quantum computing adds complexity and diversity to a well-saturated quantum field. In the quantum race competition may be fierce, but as more contenders like Honeywell enter, the field continues to diversify and develop in interesting ways.

Quantum Policy Priorities for the 46th Australian Parliament
Feature image from Quintessence Labs
Ahead of this weekend's Australian election, Project Q presents our top four quantum related policy priorities for the 46th Australian Parliament.
The Australian government has been invested in the long-term development of quantum computing since 2000. A 2016 investment boost, to the tune of $70 million AUD over five years from business, academia and the Turnbull government, has helped solidify Australia's position as a real competitor in what has been dubbed the "quantum race". By relying heavily on support from the private sector and brain-power from NSW knowledge institutions like the University of Sydney's Nano Institute and UNSW's Centre for Computation and Communication Technology (CQC2T), Australia has become recognized as a world leader in silicon-based quantum computing research. But while financial support for quantum computing has been strong, a comprehensive strategy that prioritizes benefits and minimizes harms from these technologies is not at pace.
While Australia is not alone in this position, it is at risk of falling behind. Global quantum competitors are rapidly formalizing proactive policies, in hopes of securing a position on the world stage with this technological development. In the U.S., the government is beginning to think systematically about quantum technology development and enacting policy to match this approach. China, meanwhile, has wasted no time in the coordination and execution of its national quantum policy. The E.U. has also advanced its quantum policy approach and represents the only region to do so with equity and ethics as the backbone of these policies. Whichever party is victorious on Saturday, the 46th Australian Parliament will be presented with the challenge – and the opportunity – to introduce progressive tech policies that will not only boost industry and research, but will protect citizens and pave the way for other countries to follow suit.
For Australia to remain competitive in the quantum race and be prepared for the new reality that will form in the wake of its fulfilment, the 46th Australian Parliament should prioritize the following to create a comprehensive quantum policy:
The coming age of quantum computing will result in a drastic transformation of cyber-security needs. Whether or not Australia wins the quantum race, whoever wins tomorrow's election will need to address the reality that with the realization of a fully functioning quantum computer will come the ability to hack any system. The Australian Department of Defence is already investing in quantum cryptography, supporting Canberra-based quantum cybersecurity firm Quintessence Labs (QLabs) with AU$528,000 in funding for the further development of quantum key distribution (QKD) technology. This was the largest of eight Defence Department Innovation Hub grants in 2017. It is clear this need has already been recognized by the government in relation to national defence. What is not clear, is how the Australian government will support the keepers of Australians' most sensitive data—including healthcare services, banks and businesses—to adapt to these new challenges. A lack of quantum cryptography preparedness across even these non-military sectors could result in dire security consequences for Australia.
The Australian Government should consider emulating the forward-looking policy approach stipulated by the European Commission's Joint Research Centre (JRC). The JRC stresses the importance of equipping both military and non-military service providers with a plan toward implementing future, quantum-encrypted capabilities. The report urges: "Cryptography is indeed important for applications such as preventing interception of classified information, providing governmental services, protecting critical infrastructure, and in the military field. Banks and financial institutions, data centres providers, and players in the health sector can also be potential users. A home-grown industry mastering a technique that potentially guarantees future-proof communications security can hence be seen as an issue of national security."
Chinese Collaboration
Chinese investment and influence plays an important economic and cultural role in Australia. This is a relationship that most parties have vowed to protect, enshrining it in trade and regional-relations policy. In the quantum race, however, there are concerns that Chinese collaboration on Australian quantum projects could present a national security risk. According to the aforementioned JRC report, this challenge has been identified and is being addressed by the European Commission through their quantum technologies flagship initiative.
The depth and scale of this issue has also been reported by the Australian Strategic Policy Institute (ASPI), in their report, Picking Flowers, Making Honey. The title of the report is derived from a description by the People's Liberation Army of Chinese-Western collaboration (especially in the Five Eyes countries), as "picking flowers in foreign lands to make honey in China". The report details how the PLA strategically deploys military researchers to universities in Western countries, obscuring their affiliation, and then brings them back to China so they can use the knowledge and information gleaned from their collaborations to further China's own national technology development efforts. ASPI reports that this practice essentially aids Chinese military development, especially in the emerging field of quantum computing.
While it remains unclear whether or not the Australian government and domestic research institutions are informed of this practice, no action against this strategic transfer of knowledge has so far been taken. In fact, "Among universities in Five Eyes countries, the University of New South Wales (UNSW) has published the most peer-reviewed literature in collaboration with PLA scientists.". This information should concern the incoming Australian government, as UNSW is one of the leaders in Australian quantum computing development. If Australia seeks to remain a leader in quantum computing, this is an issue that must be tackled, albeit with a delicate approach that will not impact negatively on the many positive effects of Chinese interests in Australia. According to the ASPI report, many of those who participate in this practice presented with false records, a challenge that could be tackled simply with a higher level of scrutiny over the visa application process for incoming researchers collaborating on high-value projects.
Focus on the Development of Promising Environmental and Renewable Energy Applications
Climate change is a big-ticket item in the upcoming election, and one that may play a decisive role in inducing government change. Regardless, all parties have stated a commitment to investing in renewable energy. Quantum research outside of communication and computing presents promising potential for renewables. However, quantum applications in this space require an increased level of attention and support in order to develop. The Australian government should be investing in a far broader spectrum of emerging quantum applications, such as quantum dots, which could revolutionize the solar energy industry, and quantum tunnelling, which could help to capture and transfer wasted energy. These will be the green energies of tomorrow, presenting Australia with the unique opportunity to be a global leader in this space.
Quantum Business
Already, Australia has grown and attracted a number of powerful tech start-ups and international funding, bolstering its position as a hub for quantum research. There is momentum building to make Sydney the destination for quantum investment and to cement Australia's place as the Silicon Valley of quantum development in the Southern hemisphere. Further focus on supporting the growth and development of this ecosystem could create a competitive advantage for Australia, boosting business investment and drawing the brightest minds from all over the world to solve quantum's biggest challenges.
This, in turn, could allow the Australian quantum industry to broaden the scope of its focus, expanding to the areas of research and development mentioned above. Government investment in building the desirability of Australia as a world-class quantum destination would not only help to attract critical private sector investment but could also serve to attract the talent that is now sorely needed.
All contenders on Saturday's ballot claim varying levels of commitment to prioritizing issues that the coming age of quantum computing will impact, such as cyber-security, defence, innovation and science, business, energy and environment, healthcare and regional relations. Yet no party on the election ballot has explicitly mentioned a dedicated policy for the further development and adoption of quantum technologies. Australia now has the chance to produce an agile national quantum policy that could complement and support some of the most important policy agendas already being pursued. It is clear that quantum technologies will carry a number of social and economic benefits, which will require the keen attention of government representatives in order to realize their potential. As demonstrated by the actions of Australia's global competitors in quantum development, this can be done in a number of ways. We recommend a human-centric approach that weighs the threats and benefits of quantum development with a critical eye and seeks to not only maximize the benefit of these technologies for all Australians, but also presents an example for other countries to follow suit.
Artificial Intelligence, Quantum Computing
When Quantum Meets AI: PERILS, as Two of our Future's Most Powerful Technologies Collide
May 9, 2019 May 8, 2019 By Project Q	No Comments
Part III of III
Quantum computing and artificial intelligence (AI) are disruptive technologies. They are set to transform and rupture both industry and societal networks as they challenge and displace current systems. The powerful evolution that will be ignited across disciplines if and when these technologies become fully functional and cohesive is sure to challenge modern hegemony in a number of ways. Some of these changes, as we have discussed in last week's instalment, could endow us with the tools to make this world a better and fairer place for people around the globe. Of course, the duality of light and dark also characterizes emerging technologies, and some of these changes could impose powerfully deleterious effects on society. While we have discussed some of the potentially promising applications for these technologies in the future, we also caution that there is no way of knowing exactly how these technologies will evolve, both together and separately. Industry and government cannot ensure that emerging technologies have only positive societal impacts. However, these forces certainly do have some power over the process to leverage benefits in a way that consciously produces positive impacts and opportunities to confront underlying societal challenges.
This final instalment of our quantum-AI series will caution against the type of thinking that views technological advancements as end-all-be-all solutions. Certainly, these emerging technologies present the potential for revolutionary social, economic and environmental benefits. However, if we focus only on the positive impacts these emerging technologies may have, we risk blinding ourselves to the underlying issues that they may confront but cannot solve. In this way, quantum-AI applications could produce either a Band-Aid effect or could even exacerbate certain challenges rather than "fix" them. Rather, with a human-centric approach and a forward-looking perspective, we hope these technologies can be channelled and regulated in ways that work for the benefit rather than the to the detriment of societies across the globe.
Towards a More Objective AI?
When we talk about a quantum boost to AI development it is imperative that we consider the current challenges facing machine learning today and how these might be impacted by the accelerated development of AI technologies. In last week's instalment, we explored how quantum-powered AI might enable machine learning algorithms to create a more nuanced output from more complex data sets. While this reality may ultimately manifest, it does not guarantee that enhancing AI's capacity to process larger and more complex data sets will fix its bias problem. That is because this problem is not wholly a technological one, but mostly a human one.
A recent MIT Technology Review article dives into this issue, citing a new report by the AI Now Institute, which explores AI's ongoing "diversity crisis". The report presents some staggering figures with regard to gender and racial diversity in the AI industry and argues that there will be no solution to AI's bias problem without a monumental shift in these demographics. Across both industry and academia, the percentage of Black and Latino contributors to the field of AI is no higher than 5% and the number of non-male contributors sits below 20%. With such a homogenous group of people writing AI algorithms, it is no wonder a bias exists in the technology.
Some powerful examples of the negative social impacts that have been produced through the application of AI are given in the aforementioned article: "Along the way, the technology has automated the biases of its creators to alarming effect: devaluing women's résumés, perpetuating employment and housing discrimination, and enshrining racist policing practices and prison convictions.". Clearly, these biases are not harmless and have already manifested negative social impacts across a number of sectors. This is a challenge that quantum-boosted AI will not be able to confront. If we believe that a higher-powered AI that is able to process vast amounts of data will alone solve AI's bias problem we are severely mistaken. Ignorance of these underlying, systemic issues will only serve to deepen divides and reaffirm inequalities.
This debate challenges the misconception that technology exists independent of society. Originating in the early nineties with the advent of the Internet, the idea that cyberspace would be an egalitarian realm free from notions of race, gender or identity is a belief that is still cemented in the human psyche. Though it is increasingly challenged today, the results of this belief are instituted throughout the culture and practices of the technology sector. Long-term systemic change is what will be required to displace this dynamic: From a shift in male-dominated workplace culture to hiring, retention and workplace support practices for racial and gender minorities. The journey to diminishing AI's bias problem is inherently tied to the achievement of far more diversity and better representation in AI technology development.
Impacts in the Medical Sector
Quantum-powered AI technologies promise to revolutionize healthcare systems across the globe in a number of ways. But will the further automation of healthcare services be a benefit or a detriment to patients?
Recent years have seen health care systems across the globe move towards an approach that seeks to maximize efficiency. This results in patients receiving less of their doctor's time, which is instead increasingly demanded by their computer's reporting and diagnostic systems. Likewise, changes in insurance policies over the last decade have led to the standardization of less patient-doctor contact. A 2017 systematic review of 67 countries notes that already, "For half of the world's population, primary care doctor visits last less than five minutes.". This, in turn, and coupled with the boom of Big Pharma, has resulted in most doctor's visits ending with a prescription in hand, at least in the United States.
Certainly, in the United States, the prescription of drugs is the most viable outcome from a GP visit where the patient is only allotted an average of 15 minutes of the doctor's time. This reality is already a serious challenge that has no doubt created negative societal impacts. One such example is the vicious opioid crisis currently plaguing the country, due largely to the over-prescription of opiates. While this is only one example from one country, it illustrates that the situation that has arisen in primary healthcare across the globe is extremely complex and warrants specific consideration before current systems are advanced with new technologies.
Quantum-AI technologies promise to further increase the efficiency of these systems, but there is sufficient reason to pause and ask ourselves what role this may or may not play in actually improving health outcomes for patients. The increased automation that may result from the confluence of quantum computing and machine learning could serve to further entrench healthcare systems in this fast-food style of primary care. It is not difficult to imagine how this could influence a further reliance on the diagnosis of medical conditions linked to an automated prescription of drugs. This could only serve to move us further away from a holistic approach to healthcare, in which doctors spend more time trying to understand a patient's specific circumstances in order to recommend not only drugs but also lifestyle changes in areas such as exercise, diet and sleep.
In order for the future of quantum-AI systems to function in harmony with human practitioners, a deep understanding of the intricate complexities of the current state of healthcare and the directions in which it is moving is entirely necessary. Likewise, other considerations of value when debating the topic of the role of these emerging technologies in healthcare systems should include: the cost viability of implementing new quantum-AI systems uniformly across healthcare providers, the difficulty a GP may have in deciphering diagnostic reasoning of AI systems, and the potential for privacy and ethical issues with regard to the storage of patient data, especially in the context of quantum encryption and hacking.
Impacts in Business and Government
Traditionally, the implementation of high technology in business has been slow to take hold. However, current trends point to a shift in this practice. According to Forbes: "For the first time ever, emerging technology investment has superseded customer understanding and the No. 1 thing firms want to do more to be innovative.". As the pace of emerging technology adoption in business accelerates across sectors, there is a fundamental need to apply a human-centred policy approach to the implementation of quantum and AI technology in order to keep humans "in the loop".
Technological innovation in and of itself is of little value to a business. Emerging technologies like quantum and AI do not exist in a bubble apart from society, but rather function within human-built and run systems and networks. As such, if an organisation is not flexible and adaptive enough to accommodate a mass technological shift, such as the incorporation of quantum-powered AI into financial modelling systems, the implementation may cause more problems than benefits. Again, while this challenge is specific to the implementation of new technologies, it is a people problem, not a technology problem. If the organisation itself is not adaptive enough then these implementations could be not only detrimental to the culture and wellbeing of employees but also potentially fatal to the business itself.
As with business, government systems too will need flexibility and agility in order to adopt emerging quantum-AI capabilities. Government agencies are bureaucratic and hierarchical, which can make emerging technology implementation especially challenging and time-consuming. As we have previously covered, the United States DoD has been particularly slow on the uptake of quantum technologies. When businesses and governments alike begin to consider the implementation of quantum and AI technologies, they should do so with the foresight and human-centric approach necessary in order for such system changes to take hold and function effectively. While it is challenging to regulate emerging technologies before they are fully functional in applied settings, there is a need for a strong and proactive government foresight into how quantum and AI will develop, both in tandem and in isolation of one another as well as within existing structures and systems.
Whose Role is it?
In the case of the informed and proactive regulation of emerging technologies, responsibility and control fall largely upon the shoulders of two powers: industry and government. Due to the fundamental role that the private sector plays in the development of quantum and AI, the United States provides an interesting case study. As we have debated previously on the blog, the United States' heavy reliance on Silicon Valley as its technology development machine, especially for defence purposes, comes with a host of specific challenges and advantages.
Unlike in China, where national technology investment strategies are extremely well-funded and seamlessly incorporate the power of an utterly nationalistic and committed private sector, the United States' approach leaves far more room for dissonance. Notoriously anti-establishment and globalist, Silicon Valley produces companies like Google, Amazon and Microsoft where grassroots individualism often manifests as a central business characteristic. In comparison to China's strategy, this creates a contentious and sometimes tumultuous relationship of dependence between the United States Department of Defence (DoD) and these tech giants, who it is hoped will deliver on national defence contracts.
This challenge has been dubbed by those who fear this dynamic will harm United States security interests as Silicon Valley's "techno-moralist" problem. But while this dynamic may appear as a challenge for the DoD in the race to achieve dominance over quantum and AI development, it presents an opportunity for industry to help bring the crucial lens of ethics onto the issue, which could serve a critical role in helping to regulate the development and fusion of these two technologies.
From a top-down perspective, the United States government has recently taken interest in the development of what is commonly known as ethical AI. In February of this year, a resolution, "Supporting the development of guidelines for the ethical development of artificial intelligence,", was introduced in the White House. However, this high-level conversation around the ethics of AI has yet to extend to quantum. This is due to many factors, including the public's lack of engagement with the topic of quantum technologies, which can be challenging to understand in the abstract. Nonetheless, the government of the United States' policy formation around the prospective social impacts of AI applications lends hope to the development of a similar approach to quantum technologies.
The Defence Advanced Research Projects Agency (DARPA) is the agency of the United States' DoD responsible for funding and coordinating the development of emerging technologies for military applications. It is also the biggest funder of basic science in the U.S.. While DARPA pours billions of U.S. dollars into the development of emerging technologies, funding for research into the social impact of these is severely lacking. As we have urged previously, "social impact research has the potential to make systems run smoother, more ethically and sustainably, giving an advantage to a science and technology environment that takes a long view rather than a short-term perspective.". Further, the DoD's reliance on the "techno-moralists" to deliver the technological advancements needed to maintain U.S. military supremacy also presents an important argument for a shift in this imbalance. Given the context of Silicon Valley's tech culture, this is not a debate that will be won by DoD money or muscle. Rather, it is one that must appeal to a sense of ethics. This can only be done by government demonstrating that there is a strong commitment to understanding the social impacts that the future applications of quantum-AI technologies will undoubtedly produce.
When Quantum Meets AI: PROMISES, as Two of our Future's Most Powerful Technologies Collide
Part II of III
Project Q seeks to perforate the silos built up around disciplines. We believe that the nature of science and technology is inherently social, and we strive to explore the ways in which these disciplines are cross-pollinated and how they intertwine. Likewise, the intersection of artificial intelligence (AI) and quantum physics, stemming from the disciplines of computer science and physics, respectively, demonstrates the value of building bridges between academically separated fields. This fusion presents benefits for both ends of the spectrum, promising to have an impact on the ways in which we understand and apply both quantum technology and artificial intelligence.
The emerging, interdisciplinary field of quantum machine learning is in a truly nascent stage of development. However, as demonstrated by the research cited in the introduction to this series, researchers are not waiting around for the full realization of a quantum advantage to begin testing these experimental waters. The results from early studies, using relatively low-powered quantum computers and machine learning systems, certainly lend support to the hype promising that together these technologies will make a big impact on our future. That being said, while these technologies are expected to affect a wide range of industries, there is no way to be sure of exactly how they will develop, both separately and in conjunction. The only surety is that there will undoubtedly be unexpected outcomes produced by the fusion of quantum and AI. Still, the big names in both quantum and AI development, including NASA, IBM and Microsoft, race ahead to develop these technologies for commercial and state-sponsored use.
Dual Promise
On a fundamental level, machine learning could contribute to the development of quantum computing itself. One emerging application for machine learning in quantum computing is in the formulation of complex quantum algorithms. This is a formidable challenge in quantum computing that could be confronted with the help of machine learning, in order for quantum algorithms to be designed and learned by quantum computers themselves rather than composed through the time-consuming effort of the few quantum experts. By using a physics-oriented approach to intelligent machines, complex, quantum-entangled experiments are already being designed by researchers working at the intersection of quantum and AI. Early examples of quantum experiments like this one, enabled by the power of machine learning, demonstrate the potential for AI to play a vital role in the development of quantum computing.
The promise of this application for machine learning in quantum computing is best summed up by Dr. Irfan Saddiqi, of Berkley's Quantum Nanoscience Laboratory: "Can we teach a machine quantum mechanics? Can a machine learn the rules of quantum-mechanics? The answer is, absolutely.". Saddiqi and his colleagues use recurrent neural networks (RNN), a specific type of AI algorithm that mimics the biology of the human brain to make sense of large data sets by identifying patterns from the data itself. While it should be noted that RNN cannot actually understand quantum computing in the way that a human brain can, it can produce computational results that can serve as a valuable tool for researchers. In this way, machine learning could be of important value to quantum computing by making sense of the vast amounts of data produced by quantum computers. Some predict that AI technology will eventually become a standard feature of quantum hardware for this reason.
Perhaps the most anticipated manifestation of the amalgamation of these technologies, however, comes in the form of a quantum boost to AI. Scientists are beginning to explore the question of how quantum computers could be used for intelligent data analysis. According to Canadian quantum computing company Xanadu, the potential areas of impact for quantum computing in AI include optimization, linear algebra, sampling and kernel evaluations. These four specializations of quantum computing could accelerate the development of AI to be more effective and efficient. Examples of use for these quantum capabilities in machine learning include, respectively: helping AI to evaluate hard-to-compute functions, exponentially speeding up the processing power of AI, producing data samples to train AI on, and augmenting certain functions of classical computers, such as the use of kernel methods, which can be difficult to compute classically. Today's quantum computers are well-adapted to enhance these specific functions in AI, especially in cohesion with classical computers, as they are mostly special-purpose built devices at this stage in development.
Toward a More Objective AI?
As previously discussed, new research into the feature mapping capabilities that quantum computing could perform should enhance the sophistication of data mapping that AI is capable of. This illustrates the potential for AI powered by quantum computing to surpass its current levels of efficacy, by identifying patterns in data that are not visible to classical computers. According to IBM researchers: "AI systems thrive when the machine learning algorithms used to train them are given massive amounts of data to ingest, classify and analyze. The more precisely that data can be classified according to specific characteristics, or features, the better the AI will perform.". A critical role that quantum computers could play in AI as their quantum volume increases, is to enable the computation of far more complex and vastly larger data sets through feature mapping. In less technical and more theoretical terms, perhaps this quantum capability will be able to influence more objective and less biased AI output, depending on the breadth and quality of data it is trained on.
The wisdom of the crowd theory, popularised in the Information Age by citizen-powered journalism sites such as Wikipedia or Reddit, underpins these website's success in producing surprisingly accurate and up-to-date information, given that most contributors are not "experts". As with machine learning, these websites are only as good as their data points in quality and in numbers. The wisdom of the crowd theory dictates that the larger and more diverse the pool of contributors producing information for any given article, the higher the levels of accuracy tend to be.
Quantum computing could offer machine learning a similar advantage by enabling a higher level of computational power to deal with a larger and more diverse sample of data points. It would be able to lend this advantage because the quantum properties of particles theoretically exist in a near infinite quantum state of all possible realities. The power of quantum computing lies in its ability to inhabit this quantum space, opening up the possibility for a far greater scale of computing than conventional computers can offer. With regard to machine learning, this means that patterns and features that AI algorithms look for in a data set could be sorted at a much faster pace with more efficiency than currently possible. While this theory has not been tested, perhaps quantum computing could help with AI's ever-present bias problem, by enabling machine learning to process and identify patterns in larger and more complex data sets. Further, there is hope that this quantum-endowed capability, if realized, could allow for a more nuanced reading of data and lead AI systems to new findings.
One domain where the ability of AI to pick up on subtler patterns from larger data sets, thanks to a quantum boost, could have an especially positive impact is in the medical field. There is significant hope amongst scientists that quantum computing and AI systems will revolutionize the medical sector through drug discovery, disease screening and by supporting clinical diagnosis and decision-making.
A controversial topic of discussion, it has now been shown that AI can make more accurate medical diagnoses and predictions than some doctors. While some may fear that this information will eventually lead to AI replacing doctor's jobs, the far more likely outcome is that AI could function in support of them. In fact, AI is well-suited for the role of diagnosing, a task that involves scouring information for patterns and drawing conclusions from these.
Already, computer systems play a distinct role in this practice. Diagnosing systems, known as clinical support systems (CDSSs), analyse medical data to assist in clinical decision-making. AI systems powered by quantum computing could greatly enhance the efficacy and speed of such systems, providing vital support to physicians in diagnostics and leading to better health outcomes for patients.
Quantum-powered AI could also play a significant role in drug discovery. Currently, it takes on average 12 years and $2.7 billion USD to get a new drug to market. This is an issue currently being tackled by start-ups like GTN, a company that is working to combine the power of quantum computing and AI in order to cut those numbers in half. Co-founder and CEO of GTN, Noor Shaker, has vowed to solve this problem by combining the forces of these two technologies in order to improve access to new drugs, especially in developing countries.
In the case of GTN's technology, quantum computers, which are able to conquer the complexity of chemistry problems, produce simulations of chemical interactions and feed that information into a machine learning algorithm. The algorithm can then analyse the data and search for patterns that will lead to an understanding of the compounds. According to a feature by MIT Technology Review: "Thanks to the combination of both technologies, the GTN LTD software detects new molecules that have the potential to behave like current drugs. The company's algorithms simulate, filter and select molecules that were virtually invisible to convert them into different medications".
Examples like this one demonstrate how the novel use of these two technologies could revolutionize the pharmaceutical industry, making the drug discovery process more efficient, quicker and cheaper. The knock-on effects of producing applications like this for quantum-AI technologies could have a significant impact on improving access to drugs and getting better drugs on the market faster, making life better for those living both in developed and in developing countries.
Impacts for Weather Modelling
The quantum-AI revolution is also set to make waves in precision weather-prediction capabilities. Accurate prediction of weather forecasting impacts a huge number of sectors across the globe. From business to agriculture to government, the ability to accurately predict changing weather patterns is of critical importance to society. Currently, the quality of weather forecasting is highly variable, dependant on the ability to collect and make sense of the mass amount of data produced by satellites. With the support of future quantum computers, AI systems could better analyse meteorological data in order to make clearer and more reliable weather predictions. This could lead to higher levels of disaster preparedness, especially in the case of more precariously-located developing countries, and this proliferation of more accurate information could help to improve more sustainable farming practices.
A far more insurmountable challenge in weather forecasting manifests in the long-term. Even on a very small scale, about 90% of five-day forecasts are accurate, compared to the approximately 50% accuracy rate for ten-day forecasts. Looking even further into the future, accurate weather forecasting is more or less impossible. Quantum and AI, however, could present a solution to this problem. By improving our ability to produce and make sense of vast amounts of data, quantum and AI systems could have a huge impact on our ability to create weather-forecast models far into the future. As we have previously covered, the improved ability to create accurate, long-term weather modelling could have a serious impact on our ability to verify the discourse on global warming, potentially prompting society to take action against climate change at a scale far more radical and quicker than what we are currently motivated to do. For many, something as intangible as climate change is only real once seen—perhaps the collision of quantum and AI in this space could endow us with that critical foresight before it is too late.
Impacts in the Financial Sector
In the banking sector, fraud detection techniques are already algorithmic. Classical computers, however, are slow at this task and require an abundance of power in order to perform the complex mathematics needed to detect fraud. Machine learning, driven by imminently more powerful quantum computing, could pick up on patterns and spot fraudulent activity with far greater ease and efficacy than what is currently possible using classical computing. Likewise, quantum algorithms based on AI systems are set to transform current trading practices through their joint optimization capacities. Quantum-powered AI systems could potentially play a strong role in identifying trading opportunities algorithmically, without the need for human input.
Of course, any time that the need for human input is lost, panic will rise. The fear the AI technologies will cause mass job loss across a number of sectors should not be ignored, but it should not incite panic either. Understanding the duality of the potential powers and threats posed by the fusion of quantum-AI could enable proactive policy, should governments invest the effort into understanding the social impact that these emerging technologies are sure to have.
Join us next week, as we take a deeper look into the nuances of these promises and explore the ways in which improper harnessing of these technologies could produce negative effects in our world.

Keystone Habitats were awarded the contract to remove 200m of fire damaged timber boardwalk at Greengairs Community Nature Reserve, Lanarkshire and replace it with recycled plastic (RCP) boardwalk. The works were centred on a peat wetland area which forms one of the most ecologically and diverse parts of the reserve.
Manually dismantled 200 meters of fire damaged timber boardwalk.
Installed 200 meters of RCP boardwalk.
Created 6 passing places to provide users with resting points and allow for wheelchair use.
Carried out minor landscaping to remove all traces of the timber boardwalk and restore the burned areas adjacent to the new boardwalk.
Manually dismantled the existing timber boardwalk and removed this from site using a low ground pressure tracked vehicle.
Pre-fabricated the eighty-eight 2.4 meter sections of RCP boardwalk off-site and transported these from a road-side drop off point to the path line by tracked dumper.
Each section was then adjusted by hand into their final positions and joined together with expansion strips to enable each section to expand and contract with temperature fluctuations.
Our habitats contract manager selected in-house staff to work on the project with previous experience of minimising adverse ecological impacts whilst working on designated sites.
There was no adverse impact on the designated wetland as a result of our construction activities.
The introduction of on-site construction waste was avoided.


Enna or Enna Werk was a small German optics manufacturer, based in München, active from 1920 to 1992. Enna made lenses for a number of German camera manufacturers and retailers, most notably Alpa, Balda and Porst. The company still exists, but has stopped producing camera lenses. They are now based in Wegscheid, where they manufacture plastic injection moulding equipment.
Dr. Siegfried Schäfer was the primary design engineer at Enna Werk and responsible for many of the Enna lens designs. Some of his designs are based on drafts by Ludwig Bertele, designer of the Ernostar and the famous Sonnar.
In the 1950ies and 60ies Enna was quite innovative. In 1953 they were the first one in West Germany who produced a wide-angle lens with retrofocus design for 35 mm SLR cameras, the 4.5/35 Lithagon. It was followed by the world's fastest 35 mm wide-angle, the 1.9/35 Super-Lithagon, in 1958. In 1961 the first in Germany designed telephoto zoom-lens was introduced, the 4/85-250, a very impressive lens.
See their 42mm screw lenses and their Exakta lenses. They also made lenses in 39mm screw mount sold by Corfield for the Periflex, and at least one - the Ennaston 85/1.5 - in the same mount under their own name.
In 1958 Enna introduced their Sockel-lenses (Sockel: socket) for 35 mm SLR cameras, a system where various lens units can be mounted to different camera mounts by an adapter, similar to the later Tamron Adaptall system. The adapter is capable to close the diaphragm and includes the focusing thread. There are two versions of this system, the second one was offered from 1964 to 1967; they are incompatible with each other. Version 1 is semi-automatic, the diaphragm has to be cocked seperately. Twelve different lenses can be attached, the range of the focal length is from 24 to 240 mm, adapters were made at least for the Exakta mount and the M42 thread mount. Version 2 is fully automatic, ten different lenses within the same range of focal length were offered. Adapters for Alpa and Miranda cameras were added.

Actually just knowing that the trial was sponsored by AstraZeneca saves us the trouble of even having to read the Jupiter study.
Though I did anyway, just for the laugh.
Peter, what do you think about the (JunkfoodscienceBlog-) "Obesity Paradox"-articles?
Sven, just flicked through a few (not read all of them by any means) and I think she is basically correct. To my mind the poo poo hits the fan when you STOP getting fatter. Once the fat cells say no to calories those calories then slosh around in your blood stream as elevated glucose and trigs. My only problem with obesity is that you are eating a diet that will eventually, at some point, lead your fat cells to say no to calories. Then you are in trouble. For some people this may be at BMI 25, for others at BMI 40. It's not the obesity that is the problem, more the eating style which promotes it.... And of course throw in plasticisers and anything else which might put a spanner in your metabolic works (stains, beta blockers and thiazide diuretics all spring to mind as glucose elevators, see JUPITER and diabetes incidence). I'd even accept genetics as a factor!
Being overweight with normal glucose and insulin is fine by me, though I think it gets harder to maintain this as you get heavier and your adipocytes overfill.
You get stuck in the rut of vanity though and I like weighting 64ish kgs.... This is not obligatory for health. Hee hee, you reading Windmill?
MTflight, thanks for that link. I didn't know JUPITER is actually an anagram for "Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin".
"My only problem with obesity is that you are eating a diet that will eventually, at some point, lead your fat cells to say no to calories."
According to the studies Sandy cites this doesn´t seem to be a big problem overall. Beeing overweight is associated with longevity in elderly. Do the researcher miss something or is there a causal relationship between overweight and longevity? What could that be? Or is it just an association?
Probably more telling than BMI would be hip/waist-ratio. Maybe quite a lot in the "normal BMI group" are thin with huge "beer bellies".
I think I would phrase it as "people who are able become overweight and carry it in to old age without becoming diabetic (ie without exceding their enregy storage ability) do well". Whether they do better than people of "normal" weight who HAVE exceeded their abilty to store energy is very probable. But then what about people of normal weight and normal glucose/insulin metabolism. Do they do worse that a metabolically similar heavy person? Not aware that anyone has checked this but, if the study is out there, it would make very interesting reading.
News on the eastern front: TK announced he had been asked by JK to write and publish a book on cholesterol. He mentioned something about writing in English - I doubt it, though. Anyway, can't wait...! Statins are scarily in vogue in PL too.
Since April, we have stopped consuming vegetable oils except for some rapeseed oil and using the bulk of cooking in ghee.
We eat mostly wheat with lentils.
I have lost about 4 kgs from 76 to 72.
However, I have having problems with weakness and had a fainting spell about a couple of weeks ago.
Yesterday I got some tests done (for insurance purposes).
The total cholesterol was 125 compared with 215 in August this year.
Post-dinner I frequently feel a sharp urge to sleep (passes in a few minutes) and is accompanied by some mental confusion (during telling a bedtime story to my 3 yr old daughter).
I am somewhat apprehensive that something is wrong somewhere but not able to fix and wondering if the doctors can help.
gyan (We eat mostly wheat with lentils.
Are you getting enough protein? How about high quality protein ( non-plant) that doesn't rely on amino combinations, like eggs? How about eliminating wheat in case it is damaging your gut lining?
Have you calculated your lean body mass? Perhaps the weight you have lost isn't fat but muscle, bone, and tissue, perhaps due to protein insufficiency.
Just back on line after 5 days working. Your lipid parameters look to be quite typical of someone on a starch based diet, something like Ornish. Classically saturated fats raise HDL, you either don't follow this pattern of biochemistry or you have accidentally reduced your fat intake when you switched to ghee... The drop in weight would fit with decreased calories, in fact that seems like the only way you could loose weight on a wheat/lentil based diet.
The low LDL would be appropriate for someone on a high fibre, carbohydrate based diet. This seems quite plausible on a whole food diet based on wheat and lentils. The lower fasting blood glucose would fit with this too, as on Kitava.
If your insulin sensitivity is good your post prandial glucose figures may be reasonable and if you can stay that way you might be okay. An HbA1c or a few glucometer readings over a couple of hours following a wheat/lentil meal would be interesting.
Bare in mind that I haven't eaten wheat or lentils in a very long time, so really you are way out of my personal experience. But that's how the lipid/glucose numbers look to me.
BTW this could be of interest too, just depends really on you ghee intake vs wheat/lentils and I guess on how wrong my suggestions might be!
Should I eat less wheat and more potatoes?
Are sweet potatoes a betetr option than potatoes?
(as they contain pre-vitamin A).
I forgot to mention I stopped eating eggs in August as the egg quality in my town has gone to pits. And the eggs seemed to give me stomach achs.
Well the not eating eggs fits in with the posts on G's blog about the benefits they provide vs your lipid numbers... As for potatoes vs grains vs sweet potatoes, you are well beyond what I have any idea about, bearing in mind I live on butter, dripping, egg yolks, cream and some meat with enough root vegetables to just keep out of ketosis... At a guess I'd go for the most paleo, which is sweet potatoes. I don't know what constrains you are under for food choices, personally I'm still living as cheaply as practically on UK supermarket food... Seem to be doing OK on 50g of carbs per day.
The message I get from epidemiology is that well educated health conscious people get less cancer despite whole grain consumption. Until you do an intervention study that's all epidemiology can tell you. Intervention gives you WHEL and PPT. The only intervention to show benefit was the Lyon Heart study and that was a multivariable intervention. Did do some good though.
In this case I didn't have a time to go through all Jeff's list, but it could be an educational experience.
