3D Systems To Acquire a Portion of Xerox's Oregon Based Solid Ink Engineering and Development Teams
Tweet Share LinkedIn Email
Expanded partnership leverages both companies' capabilities
Catapults 3DS' multijet printers powered by Xerox print heads
Combination cements technology and marketplace leadership
ROCK HILL, S.C. and NORWALK, Conn., January, 2014 — 3D Systems (NYSE:DDD) and Xerox (NYSE: XRX) announced a transaction designed to leverage both companies' 3D printing capabilities to accelerate growth and cement leadership positions. 3D Systems entered into a definitive agreement to acquire Xerox Corporation's Wilsonville, Oregon product design, engineering and chemistry group and related assets for $32.5 million in cash. Both companies expect the transaction to close before the end of 2013, subject to fulfillment of certain customary conditions. This agreement expands the decade and a half long collaboration between the companies, that already produced 3DS' best selling ProJet® series 3D printers.
"We are pleased to expand our relationship with an innovative partner of the caliber of Xerox and expect that acquiring some of the Xerox Wilsonville engineering team, together with their state-of the-art development labs and selected licensed IP, to catapult our 3D printers' development and manufacturing capabilities forward," said Avi Reichental, 3D Systems' President and CEO. "This bold step is consistent with our belief that we must act quickly and decisively to extend and cement our marketplace leadership position by taking full advantage of the window of unprecedented opportunity in front of us."
"This deal takes advantage of Xerox's world-class capabilities and expands our relationship with 3D Systems in the exciting and dynamic 3D printing industry," said Kevin Warren, President of Xerox Strategic Growth Initiatives. "It emphasizes how we are leveraging our expertise while we continue to evolve our business model and pursue strategic growth opportunities."
As part of this agreement, 3DS expects to add more than 100 experienced Xerox engineers and contractors specializing in product design and materials science to its global R&D team and immediately begin to operate its own facility within the Xerox Wilsonville campus. Xerox will maintain ink and print head development resources along with research relevant for digital printing and the 3D markets. In connection with this strategic investment, 3DS expects to progressively increase its annual R&D expenditures by approximately 75% to 100% over the next few years as it completes certain Xerox related engineering services commitments and fully leverages its expanded capabilities.
"The stronger our marketplace leadership, the more powerful our economic model becomes," continued Reichental. "Simply put, a solidified position translates directly to higher revenue, higher profitability and greater earnings power over time and we are willing to sacrifice short term earnings to get there faster."

ZOOM WORSHIP
Sundays at 10 am
Due to COVID-19 we will gather together on Zoom to worship every Sunday morning at 10 am. You are always welcome to join us! Please come as you are, and wear whatever you are comfortable in. As the songwriter Jim Manley put it, "Nobody here has a claim on a pew- come in and sit down, for you are a part of the family!"
During worship we will pray together, listen to a message from the Pastor, share our joys and concerns, and sing songs that reflect and build on the theme for the day.

Permanent residence permit in Ukraine by marriageimmigrationukraine2019-03-08T15:13:31+03:00
Section Map
Another frequently used effective method of getting a permanent residence permit in Ukraine is through marriage. Our research demonstrates that more than 90% of all permanent residence permits issued in Ukraine are marriage-related. Besides, our practice showed that quite often marriage is used only as a technical instrument for getting legalized in Ukraine, but not as an ultimate goal. Regrettably, but international love is turning into a dynamic market here, and, finding an agreeable bride or bridegroom in Ukraine is no longer a challenge.
The law recognizes two types of marriages, which may be used as a ground for getting a permanent residence permit in Ukraine.
MARRIAGE WITH THE CITIZEN OF UKRAINE.
If your beloved one is a citizen of Ukraine, you are fully entitled to apply for the permanent residence permit in Ukraine on condition that you have legitimately resided in Ukraine for more than two years.
However, you should take into consideration the following important issues:
Place of marriage registration. There is no critical difference where the marriage is concluded. Ukrainian law recognizes both marriages, which have been concluded in Ukraine, as well as those, which have been registered abroad. However, you should make sure that your foreign marriage certificate, confirming your marital status with the citizen of Ukraine, has been either duly translated for use in Ukraine or that it has apostil;
Sharing abode with your partner. Although it is naturally expected from a husband and a wife, neither the immigration law of Ukraine requires living together, nor sets forth that spouses should have the same place of registration. However, living or having the same registered place of residence may be useful, because the State migration service of Ukraine may hamper the process if there are suspicions that your marriage is not a genuine one. We are particularly skilled in convincing Ukrainian immigration authorities that marriages of our clients are the real ones, even if they live separately from their spouses (even if they live in different counties);
Legality of the marriage. It is also essential that marriage is entirely legal under the laws of Ukraine. Among other aspects, Ukrainian immigration law says that polygamy, marriages with minors, marriages, concluded under duress, and same-sex matrimonies are not recognized here. If your marriage with a citizen of Ukraine is for some reason declared void, your right to the permanent residence permit in Ukraine becomes automatically annulled;
Continuity of the marriage. In order to qualify for a permanent residence permit in Ukraine, your marriage should not be interrupted during the two years. In the event, your marriage is for some reason dissolved, and you marriage another Ukrainian citizen (or re-marry your 'original' Ukrainian spouse), the calculation of the two-year period restarts. In other words, if you were married to a Ukrainian citizen for one year and eleven months, then divorces, and marries another Ukrainian, you will have to wait another two years for getting your permanent residence permit. However, if you decide to divorce after your permanent residence permit has been issued, the validity of your residence in Ukraine is nevertheless preserved. That is why many foreigners often use this strategy for legalizing their stay in Ukraine;
Medical examination and certificate of good conduct. In contrast to other situations, those, who apply for the Ukrainian citizenship by marriage with a citizen of Ukraine, are exempted from undergoing a medical examination and producing a certificate of good conduct from the police authorities of the original country. However, certificate of good conduct from the Ukrainian police should be provided. If you have a criminal record in Ukraine, unpaid administrative fines or you violated Ukrainian immigration law in any form, serious complications may occur. Though it is highly advisable avoiding them, our lawyers are particularly experienced in handling the problems like these;
Submission of the documents to the State migration service of Ukraine. It is also vital remembering that when your partner should accompany you during the visit to the Immigration Office. He also should sign a petition there. Practically, it means that your Ukrainian spouse should be physically in Ukraine when the application is launched;
The number of permanent residence permits issues in Ukraine annually is strictly subjected to the quota system. Practically, that means that the Immigration Office of Ukraine may not issue more permits than decided by the government. The quotas are published annually. There are approximately 2,000 quotas opened every year (usually the quotas are announced on March-April). In contrast to getting a permanent residence permit in Ukraine under other grounds, when you are married to a Ukrainian citizen, the quota system is not applied to your case. In other words, even if the other applicants have used all quotas, your application will nevertheless be granted;
Permanent residence permit is the first (and the most important) step to citizenship. Permanent residence permit is a precondition for getting Ukrainian citizenship through marriage with a Ukrainian citizen. Thus, one of the documents requested by the Ukrainian Immigration in the process of getting Ukrainian citizenship is the permanent residence permit. Therefore, if you decide to apply for Ukrainian citizenship by marriage with a Ukrainian citizen, getting a permanent residence permit first is important.
Important conclusions.
As it has been illustrated above, your marriage with a Ukrainian citizen is a critical element for getting a permanent residence permit in Ukraine under this ground. The marriage should be entirely legal, and your spouse should formally support your decision to apply for a permanent residence permit in Ukraine.
In addition to that, it is important to decide, which legal option will be used to legalize your stay in the country while you are waiting for your permanent residence permit to be issued by Ukrainian immigration authorities. As we described before, Ukrainian State migration service has 12 months for assessing your application, which is beyond the duration of any visa which can be possibly issued. The first option for solving this problem is getting a temporary residence permit, which will allow you to stay in Ukraine for 12 months with the possibility of prolongation for the same period. The second solution, which may be possibly employed in this context, is to contact us for help. We will file a special motion to speed up the process. It will take 6-8 weeks to get a permanent residence permit by marriage with our support in this case.
MARRIAGE WITH A FOREIGNER, WHO HAS A PERMANENT RESIDENCE PERMIT IN UKRAINE.
By far, it is the fastest method of getting a permanent residence permit in Ukraine nowadays. In contrast to getting a permanent residence permit through marriage with a citizen of Ukraine, this method allows us getting a permanent residence permit in Ukraine almost instantaneously. However, several important considerations should be taken into account in this case:
Legality of the immigration status of your spouse. First and foremost, it is imperative that the permanent residence permit of your spouse in Ukraine in 100% legal. In other words, his immigration process should be completed with no violations of the immigration or other laws of Ukraine;
Continuity of the marriage. In contrast to the situation when your spouse is a citizen of Ukraine, there is no requirement to stay married for two years before applying for permanent residence in Ukraine. In other words, you may virtually file your application with the Immigration Office of Ukraine immediately after your marriage is registered or recognized in Ukraine;
Entry to Ukraine. In contrast to other cases of issuing a permanent residence permit in Ukraine, in this case, the law allows you to enter Ukraine with any kind of visa, even a tourist one. In other words, you may practically enter Ukraine as a tourist, get married here with a foreigner, who has a permanent residence permit here, and then to get a permanent residence permit yourself;
Permanent residency in Ukraine cannot be annulled. In other words, even if you decide to divorce the next day after your permanent residence permit has been issued, in contrast to temporary residence permit by marriage, your residence permit will preserve its validity;
The number of permanent residence permits issues in Ukraine annually is strictly subjected to the quota system. Practically, that means that the Immigration Office of Ukraine may not issue more permits than decided by the government. The quotas are published annually. There are approximately 2,000 quotas opened every year (usually the quotas are announced on March-April). Getting a permanent residence permit in Ukraine under this approach is subject to the quotas, meaning that only a certain number of residence permits are issued annually. If your application is launched after the quotas are exhausted, there will be no other option, but to wait until the new quotas are passed;
Waiting for the residence permit. While waiting for the permanent residence permit, your stay in Ukraine should be entirely legal. The law says that the Immigration office has up to 12 months to decide whether your application should be satisfied or not. During this time your stay in the country should be legal. The first option for solving this problem is getting a temporary residence permit, which will allow you to stay in Ukraine for 12 months with the possibility of prolongation for the same period. The second solution, which may be possibly employed in this context, is to contact us for help. We will file a special motion to speed up the process. It will take 6-8 weeks to get a permanent residence permit by marriage with our help in this case.
Overall, getting a permanent residence permit in Ukraine by marriage with a foreigner, who has permanent residency permit in Ukraine, is the fastest method of acquiring lifetime economic, business and social rights in Ukraine. In contrast to other methods of legalizing your stay in Ukraine, this approach has two essential advantages: there is no need to wait two years after your marriage is registered, and you may not be deprived of the residency rights in Ukraine if your marriage is for some reasons dissolved after the permanent residence permit has been issued.

Attack on Capitol Partially Coordinated on Twitter. Will Apple, Google and Amazon Ban It Now?
Posted by -NO AUTHOR- | Jan 13, 2021 | PJ Media | 0 |
https://pjmedia.com/news-and-politics/matt-margolis/2021/01/13/attack-on-capitol-partially-coordinated-on-twitter-will-apple-google-and-amazon-ban-it-now-n1336583
The FBI warned law enforcement agencies prior to the assault on the U.S. Capitol last week that there would be potential violence, reports the Associated Press. This report contradicts earlier statements that they were caught off-guard by the incident.
In the aftermath of the incident, the liberal media perpetuated the claim that President Trump incited the violence, and this was used as a pretext by big tech to ban him from various platforms. He was suspended from Facebook for at least a week and was permanently banned from Twitter, as were several others connected to Trump and his efforts to expose voter fraud in the 2020 election.
But big tech wasn't finished. Both Google and Apple removed the app Parler from their app stores, claiming the free speech alternative social media platform was used to coordinate the assault on the Capitol. However, according to the Associated Press, Twitter was also used for this purpose.
Defense and National Guard officials, including McCarthy, have said in interviews over the past several days they were told by D.C. that they believed the protests would be similar to the ones on Nov. 14 and Dec. 12. And they said that federal law enforcement authorities said that there was activity on Twitter, but that they weren't expecting the level of violence they ultimately saw last Wednesday.
Activity on Twitter? Wasn't "activity" on Parler the excuse for dropping the app from the Google Play and Apple app stores, and for Amazon to stop hosting them?
Apple, Google, and Amazon now have a choice: Either restore Parler or ban Twitter. If they don't, Parler, which is now suing Amazon for breach of contract, can now claim with evidence that they were discriminated against, and can similarly sue Apple and Google for discrimination.
Matt Margolis is the author of Airborne: How The Liberal Media Weaponized The Coronavirus Against Donald Trump, and the bestselling book The Worst President in History: The Legacy of Barack Obama. You can follow Matt on Twitter, Facebook, Parler, Gab, MeWe, Rumble, and CloutHub.

England Six Nations Betting Odds
Richard Anderson | 10.12.2010
Martin Johnson's time in charge of the England rugby team hasn't been without it's difficulties, but things have been slowly getting better for England on the pitch.
Their improved form has seen them installed as favourites in the Ladbrokes Six Nations betting to win the championship at 15/8.
England enjoyed a decent but not spectacular autumn, with an excellent 35-18 win over Australia being tempered by convincing defeats against New Zealand and South Africa.
However, England are worthy of their position as favourites in the Six Nations rugby betting, with Johnson already naming a strong elite squad of 33 players ahead of their first Six Nations game against Wales on 4th February.
With Ladbrokes offering a free £25 bet for new customers who sign up here, a £25 stake on an English win in the Six Nations would return £72 which seems like a great bet considering their improved form.
A trio of French-based players – James Haskell, Tom Palmer and Johnny Wilkinson – will provide the experience for an England squad littered with young, unproven players. Foremost is Wasps No.9 Joe Simpson who has been impressive for the London side this season, but has yet to win a cap.
England are 5/1 in the Six Nations betting to win the Grand Slam, but they will have their work cut out, with hard trips to Wales and Ireland awaiting them.
However, a bet on England to win the Six Nations for the first time since 2003 could be well worth a bet at 15/8.
A £25 bet on England to win the Grand Slam could see a return of £150. New Ladbrokes customers can sign up here for a free £25 bet.

\section{Classical uncertainty on the initial state}

The operational protocol that we are introducing in this paper does not reproduce the same results of the two-point measurement (TPM) scheme even in the absence of coherence in the initial state $\rho_{\rm i}$. There is indeed a discrepancy originating from a classical uncertainty on even diagonal (in the initial energy basis) $\rho_{\rm i}$ that is retained in our scheme. Despite this aspect is in agreement with the theses of the no-go theorem~\cite{Perarnau-LlobetPRL2017_SM} as explained in the main text, it is worth understanding it in more detail. In this regard, let us now substitute the density operator
$\varrho \equiv \sum_{r}p_{\rm i}^{(r)}\rho_{\rm i}^{(r)} = \sum_{r}p_{\rm i}^{(r)}\Pi_{\rm i}^{(r)}$ (mixed quantum state diagonal in the energy basis of the system at $t_{\rm i}$, i.e., $[\varrho,H(t_{\rm i})]=0$) as input quantum state $\rho_{\rm i}$ in Eq.~(2) of the main text. One finds that
\begin{eqnarray}\label{eq:eq_1}
{\rm P}_{\rm coh}(\Delta E) &=& \sum_{k,\ell}p_{\rm i}^{(\ell)}p_{\rm f}^{(k)}\delta(\Delta E - \Delta E_{k,\ell})
= \sum_{k,\ell}{\rm Tr}(\Pi_{\rm i}^{(\ell)}\rho_{\rm i}){\rm Tr}(\Pi_{\rm f}^{(k)}\Phi_{t_{\rm f}}[\rho_{\rm i}])\delta(\Delta E - \Delta E_{k,\ell})\nonumber \\
&=& \sum_{k,\ell,r_{1},r_{2}}p_{\rm i}^{(r_1)}p_{\rm i}^{(r_2)}{\rm Tr}(\Pi_{\rm i}^{(\ell)}\Pi_{\rm i}^{(r_1)}){\rm Tr}(\Pi_{\rm f}^{(k)}\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(r_2)}])\delta(\Delta E - \Delta E_{k,\ell})\nonumber \\
&=& \sum_{k,r_{1},r_{2}}p_{\rm i}^{(r_1)}p_{\rm i}^{(r_2)}{\rm Tr}(\Pi_{\rm f}^{(k)}\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(r_2)}])\delta(\Delta E - \Delta E_{k,r_{1}})
= \sum_{k,r_{1},r_{2}}p_{\rm i}^{(r_{1})}p_{\rm f,i}^{(k,r_{2})}\delta(\Delta E - \Delta E_{k,r_{1}}),
\end{eqnarray}
where we have used the relations
${\rm Tr}(\Pi_{\rm i}^{(\ell)}\Pi_{\rm i}^{(r_1)}) = \delta(\ell-r_{1})$ and
$p_{\rm f,i}^{(k,r_{2})} \equiv p_{\rm i}^{(r_2)}{\rm Tr}(\Pi_{\rm f}^{(k)}\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(r_2)}]) = p_{\rm i}^{(r_2)}p_{\rm f|i}^{(k,r_2)}$
with $p_{\rm f,i}^{(k,r_{2})}$ joint probabilities.

From Eq.~(\ref{eq:eq_1}) one can deduce that
${\rm P}_{\rm coh}(\Delta E) = {\rm P}_{\rm TPM}(\Delta E)$ if and only if the initial state is chosen as one of the eigenstates of the initial Hamiltonian, such that $\Delta E_{k,r_{1}} = \Delta E_{k,r_{2}}$. Indeed, in such a case
\begin{equation}\label{eq:eq_2}
{\rm P}_{\rm coh}(\Delta E) = \sum_{r_1}p_{\rm i}^{(r_1)}\sum_{k,r_{2}}p_{\rm f,i}^{(k,r_{2})}\delta(\Delta E - \Delta E_{k,r_{2}})
= \sum_{r_1}p_{\rm i}^{(r_1)}{\rm P}_{\rm TPM}(\Delta E) = {\rm P}_{\rm TPM}(\Delta E) \ .
\end{equation}

It is then clear that an initial uncertainty on which eigenstate of the Hamiltonian needs to be propagated, due to the fact that in the EPM protocol the initial measurement is \textit{virtual}, determines an additional uncertainty on the energy statistics,
which is reflected in the discrepancy between the two methods. The latter is provided by the arbitrariness of the inequality $\Delta E_{k,r_1}\neq\Delta E_{k,r_2}$, which is due to the lack of initial projective measurement and makes it impossible to reduce the two summations in Eq.~\eqref{eq:eq_1} to a single one as in the TPM case.

\section{Recovering the TPM statistics}
\label{sec:app_rec_class_limit}

As stated before, the energy change probability distribution ${\rm P}_{\rm coh}$ does not reduce to the one from the TPM scheme unless the initial state of both protocol is an energy eigenstate. Considering again an initial state diagonal in the energy eigenbasis, it can be easily seen that, to find the same statistics of $\Delta E$ as given by a TPM protocol, Eq.~(2) of the main text has to be employed as many times as the number of probabilities $p_{\rm i}^{(r)}$ that define the initial density operator $\varrho=\sum_{r}p_{\rm i}^{(r)}\Pi_{\rm i}^{(r)}$, each time initializing the quantum system in one of the projectors $\Pi_{\rm i}^{(r)}$. In doing this, the corresponding probability distribution of $\Delta E$ turns out to be
\begin{eqnarray}\label{conventional_prob_E}
  &{\rm P}_{\rm coh}(\Delta E) = \displaystyle{\sum_{r}p_{\rm i}^{(r)}\sum_{k,\ell}\delta(\Delta E - \Delta E_{k,\ell})\delta(\ell-r){\rm Tr}(\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(r)}]\Pi_{\rm f}^{(k)})}&\nonumber \\
  &= \displaystyle{\sum_{k,r}\delta(\Delta E - \Delta E_{k,r})p_{\rm f|i}^{(k,r)}p_{\rm i}^{(r)}} \equiv {\rm P}_{\rm TPM}(\Delta E) \,&
\end{eqnarray}
where $p_{\rm f|i}^{(k,r)} \equiv {\rm Tr}(\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(r)}]\Pi_{\rm f}^{(k)})$ is the transition probability to measure the final energy $E^{(k)}_{\rm f}$ conditioned to have obtained $E^{(r)}_{\rm i}$ at $t=t_{\rm i}$. Only in this way, the proposed formalism falls
into the category of FT protocols~\cite{LostaglioPRL2018_SM}, so that we can recover the conventional statistics of energy change as provided by the TPM scheme. This result is not surprising, since we are now analyzing a situation in which a possible first energy measurement at $t=t_{\rm i}$ would not introduce any disturbance to the evolution of the system. As a further remark, also notice that with this approach the notion of quasi-probabilities is not directly used~\cite{AllahverdyanPRE2014_SM,LevyArxiv2019_SM}.

\section{Analysis of the $1$st and $2$nd energy statistical moments}

In this section, we provide the analytical expressions of the $1$st and $2$nd statistical moments of the proposed energy change distribution in comparison with the ones obtained by the TPM protocol and the Micadei-Landi-Lutz (MLL) protocol in Ref.~\cite{Micadei_SM}. In doing this, we recall that the initial state $\rho_{\rm i}$ in Ref.~\cite{Micadei_SM} is expressed in terms of its eigenstates with notation $\sum_{s}p^{(s)}|s\rangle\!\langle s|$, which is the same that we will use in the following. We list below all the formulas of the joint probability $p(E_{\rm i}^{(\ell)},E_{\rm f}^{(k)})$
and the $1$st and $2$nd statistical moments of $\Delta E$ that one can obtain from the three methods.\\ \\
\textbf{EPM protocol proposed in the present paper:}
\begin{eqnarray}
    && p(E_{\rm i}^{(\ell)},E_{\rm f}^{(k)}) = {\rm Tr}(\rho_{\rm i}\Pi_{\rm i}^{(\ell)})\,{\rm Tr}(\Phi_{t_{\rm f}}[\rho_{\rm i}]\Pi_{\rm f}^{(k)}) \\
    && \langle\Delta E\rangle = {\rm Tr}({H}(t_{\rm f})\Phi_{t_{\rm f}}[\rho_{\rm i}]) - {\rm Tr}(H(t_{\rm i})\rho_{\rm i}) \\
    && \langle\Delta E^2\rangle = {\rm Tr}({H}^2(t_{\rm i})\rho_{\rm i}) + {\rm Tr}({H}^2(t_{\rm f})\Phi_{t_{\rm f}}[\rho_{\rm i}]) - 2\,{\rm Tr}(\Phi_{t_{\rm f}}[\rho_{\rm i}]{H}(t_{\rm f}))\,{\rm Tr}(\rho_{\rm i}{H}(t_{\rm i})) \ . \label{eq:app_2nd_moment}
\end{eqnarray}\\
\textbf{MLL protocol:}
\begin{eqnarray}
    && p(E_{\rm i}^{(\ell)},E_{\rm f}^{(k)}) = \sum_s p^{(s)}{\rm Tr}(|s\rangle\!\langle s|\Pi_{\rm i}^{(\ell)})\,{\rm Tr}(\Phi_{t_{\rm f}}[|s\rangle\!\langle s|]\Pi_{\rm f}^{(k)}) \\
    && \langle\Delta E\rangle = {\rm Tr}({H}(t_{\rm f})\Phi_{t_{\rm f}}[\rho_{\rm i}]) - {\rm Tr}({H}(t_{\rm i})\rho_{\rm i}) \\
    &&  \langle\Delta E^2\rangle = {\rm Tr}({H}^2(t_{\rm i})\rho_{\rm i}) + {\rm Tr}({H}^2(t_{\rm f})\Phi_{t_{\rm f}}[\rho_{\rm i}]) - 2\,\sum_s p^{(s)}{\rm Tr}(\Phi_{t_{\rm f}}[|s\rangle\!\langle s|]{H}(t_{\rm f}))\,{\rm Tr}(|s\rangle\!\langle s|{H}(t_{\rm i})) \ . \label{eq:app_2nd_moment_MLL}
\end{eqnarray}\\
\textbf{TPM protocol:}
\begin{eqnarray}
    && p(E_{\rm i}^{(\ell)},E_{\rm f}^{(k)}) = {\rm Tr}(\rho_{\rm i}\Pi_{\rm i}^{(\ell)})\,{\rm Tr}(\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(\ell)}]\Pi_{\rm f}^{(k)}) \\
    && \langle\Delta E\rangle = {\rm Tr}\left(H(t_{\rm f})\Phi_{t_{\rm f}}\left[\sum_{\ell}{\rm Tr}(\rho_{\rm i}\Pi_{\rm i}^{(\ell)})\Pi_{\rm i}^{(\ell)}\right]\right) - {\rm Tr}(H(t_{\rm i})\rho_{\rm i}) \\
    &&  \langle\Delta E^2\rangle = {\rm Tr}(H^2(t_{\rm i})\rho_{\rm i}) +
    {\rm Tr}\left({H}^2(t_{\rm f})\Phi_{t_{\rm f}}\left[\sum_{\ell}{\rm Tr}(\rho_{\rm i}\Pi_{\rm i}^{(\ell)})\Pi_{\rm i}^{(\ell)}\right]\right) - 2\,\sum_{\ell}E_{\rm i}^{(\ell)}{\rm Tr}({H}(t_{\rm f})\Phi_{t_{\rm f}}[\Pi_{\rm i}^{(\ell)}])\,{\rm Tr}(\rho_{\rm i}\Pi_{\rm i}^{(\ell)}) \ .
\end{eqnarray}

Within the TPM protocol, an initial measurement of the system Hamiltonian at $t=t_{\rm i}$
and a final one at $t=t_{\rm f}$ on the conditional evolved states are performed.
In order to get the corresponding conditional probability, the system has to be
separately initialized in each eigenstate of ${H}(t_{\rm i})$, respectively.

Concerning the MLL protocol, for the sake of experimentally characterise the energy change
probability distribution, one needs to initialize the system in the eigenstates
of the initial density matrix $\rho_{\rm i}$. This operation could be equivalently carried
on by performing an initial measurement of the observable
$\mathcal{O}\equiv\sum_{s}o_{s}|s\rangle\!\langle s|$, in general not
commuting with ${H}(t_{\rm i})$. Indeed, according to the MLL protocol,
the final energy measurement is performed on the evolved eigenstate $|s\rangle\!\langle s|$ of the initial state and the results are then
weighted with the probabilities $\{p^{(s)}\}$.

Finally, in our EPM protocol, the initial state $\rho_{\rm i}$ is arbitrary
and the final energy measurement is performed on the evolved initial state
without any need to initialize the system in a different state.
The energy change probability distribution is obtained by weighting these
final probabilities with the ones concerning the initial virtual energy measurement,
which are accessible from the knowledge of the initial state.

One can observe that the average energy change $\langle\Delta E\rangle$
provided by the EPM protocol and the MLL protocol are the same, differently to
the one from the TPM protocol for which the mean final energy measured at $t=t_{\rm f}$
does not contain any contributions from initial coherence terms in $\rho_{\rm i}$.
Furthermore, regarding the $2$nd moment $\langle\Delta E^{2}\rangle$, the three protocols
differ again for the way in which the initial energy outcomes
(eigenvalues of ${H}(t_{\rm i})$) are taken into account in
relation to $\rho_{\rm i}$. Only our (operational) method makes no assumptions
about $\rho_{\rm i}$, since we completely remove the need to perform
any initial projective measurement.
However, in general, if the initial state $\rho_{\rm i}$ is pure,
the second moments~\eqref{eq:app_2nd_moment} and \eqref{eq:app_2nd_moment_MLL} coincide,
while, as shown above in
Section II, $\eqref{eq:app_2nd_moment}$ coincides with the second moment
obtained by applying the TPM protocol for an initial state corresponding to an
eigenstate of ${H}(t_{\rm i})$.

It is also interesting to note that the probability distribution from the EPM protocol corresponds to the product of the marginals of the MLL-protocol probability distribution~\footnote{The authors thank Gabriel T. Landi for pointing this out to us.}.
In particular, the (informational) price that we have to pay due to \textit{not} performing any initial measurement, with respect to the MLL protocol that requires a greater knowledge of the state and dynamics, can be quantified by the mutual
information between the two probability distributions, i.e.,
\begin{equation}
    \mathcal{I}({\rm P}_{\rm MLL},{\rm P}_{\rm coh})=\sum_{k,\ell}p_{\rm MLL}^{(k,\ell)}\log\left(p_{\rm MLL}^{(k,\ell)}/p_{\rm coh}^{(k,\ell)}\right).
\end{equation}
$\mathcal{I}({\rm P}_{\rm MLL},{\rm P}_{\rm coh})$ encodes the cost of our assumption of the statistical independence between the final energy measurement
and the initial virtual one with respect to the MLL scheme.
\\ \\
Let us summarize what we have discussed so far concerning the connection of the proposed protocol with the TPM and MLL schemes:
\begin{itemize}
    \item
    For an initial state $\rho_{\rm i}$ diagonal in the energy eigenbasis, the MLL and TPM protocols provide the same joint probability $p(E_{\rm i}^{(\ell)},E_{\rm f}^{(k)})$, while the EPM protocol's probability distribution differ from them.
    \item
    For an initial pure state, not necessarily an eigenstate of the initial Hamiltonian, the joint probabilities from our method and the MLL protocol coincide.
    \item
    In the special case of initial pure energy eigenstate, all three protocols give the same result.
\end{itemize}
A first element of difference between the EPM protocol and the TPM and MLL ones
is given by a classical uncertainty on the initial state $\rho_{\rm i}$.
This is due to the fact that we are assuming to not know the single pure
components that decompose the initial state $\rho_{\rm i}$, or at least the effect
of the dynamics on them separately. Operationally, both the TPM (explicitly) and the
MLL (implicitly) need to assume the knowledge about the evolution of the pure components
of the system initial state (either in the energy eigenbasis or in its eigenbasis),
which are then evolved and give rise to conditional probabilities. The proposed protocol
does not assume this knowledge and it is thus nicely amenable
for experimental implementations with minimal resources.

\section{Energy change characteristic function}
Here, we provide the mathematical details for the derivation of the characteristic
function associated to the energy change distribution both from the proposed method and the
MLL and TPM protocols.
The characteristic function from the three methods are respectively equal to
\begin{align}
    & \mathcal{G}(u) = {\rm Tr}(e^{-iu{H}(t_{\rm i})}\rho_{\rm i})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\rho_{\rm i}])\label{eq:app_G_coh} \\
    & \mathcal{G}_{\rm MLL}(u) = \sum_s p^{(s)} {\rm Tr}\left(|s\rangle\!\langle s| e^{-iu{H}(t_{\rm i})}\right)\,{\rm Tr}\left(\Phi_{t_{\rm f}}[|s\rangle\!\langle s|]e^{iu{H}(t_{\rm f})}\right) \\
    & \mathcal{G}_{\rm TPM}(u)={\rm Tr}(e^{iuH(t_{\rm f})}\Phi_{t_{\rm f}}[e^{-iuH(t_{\rm i})}\mathcal{P}])

\end{align}
with $u\in\mathbb{C}$ complex number {and $\mathcal{P}$ the diagonal part of the initial state in the energy basis}. Also at the level of the characteristic function of
the energy change distribution, we can single out coherence contributions. In particular,
by taking $\rho_i=\mathcal{P}+\chi$ in~\eqref{eq:app_G_coh}, one has
\begin{align}
    \mathcal{G}(u) &= {\rm Tr}(e^{-iu{H}(t_{\rm i})}\rho_{\rm i})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\rho_{\rm i}])\nonumber \\
    &={\rm Tr}(e^{-iu{H}(t_{\rm i})}\mathcal{P})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\mathcal{P}])+{\rm Tr}(e^{-iu{H}(t_{\rm i})}\mathcal{P})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\chi])\nonumber \\
    &\equiv\mathcal{G}_{\mathcal{P}}(u)+\mathcal{G}_{\mathcal{\chi}}(u),
\end{align}
where $\mathcal{G}_{\mathcal{P}}(u) \equiv {\rm Tr}(e^{-iu{H}(t_{\rm i})}\mathcal{P})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\mathcal{P}])$ and
$\mathcal{G}_{\mathcal{\chi}}(u) \equiv {\rm Tr}(e^{-iu{H}(t_{\rm i})}\mathcal{P})\,{\rm Tr}(e^{iu{H}(t_{\rm f})}\Phi_{t_{\rm f}}[\chi])$. As a result,
$\mathcal{G}_{\chi}=0$ when $\chi=0$ and $\mathcal{G}_{\mathcal{P}}=\mathcal{G}_{\rm TPM}$
as far as $\mathcal{P}$ is a projector associated to a system energy eigenspace.

Given the expression of $\mathcal{G}$ for the EPM protocol,
we present in the following a derivation of Eq.\,(8) of the main text. We have
\begin{align}
    \langle e^{-\beta\Delta E}\rangle&={\rm Tr}(\rho_{\rm i}e^{\beta H(t_{\rm i})}){\rm Tr}(\Phi_{t_{\rm f}}[\rho_{\rm i}]e^{-\beta H(t_{\rm f})})\nonumber\\
    &={\rm Tr}[\mathcal{P}e^{\beta H(t_{\rm i})}]\left({\rm Tr}\left(\Phi_{t_{\rm f}}[\mathcal{P}]e^{-\beta H(t_{\rm f})}\right)+{\rm Tr}\left(\Phi_{t_{\rm f}}[\chi]e^{-\beta H(t_{\rm f})}\right)\right),
\end{align}
where in the second line we have used $\rho_{\rm i}=\mathcal{P}+\chi$ with ${\rm Tr}(\chi)=0$ and $\mathcal{P}$ the diagonal part of the initial state in the energy basis. Further assuming $\mathcal{P}=\rho_{\rm i}^{\rm th}$ and multiplying by $Z_{\rm i}/Z_{\rm f}$ both sides of the equation above, we obtain
\begin{align}\label{eqJarSI}
    \langle e^{-\beta(\Delta E-\Delta F)}\rangle&={\rm Tr}(\mathbb{I})\left({\rm Tr}\left(\Phi_{t_{\rm f}}[\rho_{\rm i}^{\rm th}]\rho_{\rm f}^{\rm th}\right)+{\rm Tr}\left(\Phi_{t_{\rm f}}[\chi]\rho_{\rm f}^{\rm th})\right)\right)=d\,\left({\rm Tr}\left(\Phi_{t_{\rm f}}[\rho_{\rm i}^{\rm th}]\rho_{\rm f}^{\rm th}\right)+{\rm Tr}\left(\Phi_{t_{\rm f}}[\chi]\rho_{\rm f}^{\rm th})\right)\right)
\end{align}
where $\rho_{\rm i(f)}^{\rm th} \equiv \displaystyle{e^{-\beta {H}(t_{\rm i(f)})}/{Z_{\rm i(f)}}}$ are the two thermal (reference) states at inverse temperature $\beta$ referring, respectively, to the initial and final time instants of the protocol, and we have used the fact that $\Delta F = -\beta^{-1}\ln\left(Z_{\rm f}/{Z_{\rm i}}\right)$.
We refer to Fig.~\ref{newfig2} below for the comparison between the results provided by Eq.~\eqref{eqJarSI} and those coming from the TPM protocol in the case of an open three-level system with time-dependent Hamiltonian and coupled to three thermal baths, one for each level. Instead, Fig.~\ref{newfig} \textbf{(b)} shows the same comparison for the case in which the three-level system is not coupled to the thermal environment, thus evolving unitarily.
The main difference between the open and close systems lays in the fact that, for the open quantum case of Fig.~\ref{newfig2}, also the TPM protocol's result deviates from unity.

\section{Experimental Results}

In order to illustrate the effects of initial coherence on energy fluctuations, as singled out by our EPM protocol, in this section we provide more details on the experiments performed with IBM Quantum Experience (IBMQ) and discussed in the main text.

\subsection{Two-qubit state initialization}

As discussed in the main text, the initial (pure) state of the two-qubits is prepared to be of the form $\rho_{\rm i} =|\psi_\text{i}\rangle\!\langle\psi_\text{i}| = \rho^{\rm th}+\chi$ where the corresponding diagonal part (in the computational basis of the quantum gate) is a thermal state of the local Hamiltonian $H_A+H_B=\epsilon(\sigma_z^{(A)}\otimes\mathbb{I}^{(B)}+\mathbb{I}^{(A)}\otimes\sigma_z^{(B)})$. The initial state, to be implemented on IBMQ, is pure and can be generated by directly acting on the default state $|00\rangle$ of the information carriers via local gates. We request a pure state whose diagonal part $\rho^\text{th}$ takes the thermal-like form
\begin{equation}

    \rho^{\rm th} =\frac{1}{(\cosh (2 \beta  \epsilon )+1)^2} \rm{diag}\left\{{e^{-2 \beta  \epsilon } \cosh ^2(\beta  \epsilon )},{\cosh ^2(\beta  \epsilon )},{\cosh ^2(\beta  \epsilon )},{e^{2 \beta  \epsilon } \cosh ^2(\beta  \epsilon )}\right\}
\end{equation}
with $\beta$ inverse temperature. As any two-qubit state can be expressed, in the computational basis, as $|\psi\rangle\!\langle\psi|=\sum_{k,\ell=0}^{3}a_{k\ell}|k\rangle\!\langle\ell|$, we require
\begin{equation}\label{phases}
a_{k\ell}=e^{i\phi_{k\ell}} \sqrt{\rho^{\rm th}_{k\ell,k\ell}}\quad\forall{k,l=0,\ldots,3}.
\end{equation}
The corresponding state $|\psi_{\rm i}\rangle$ can be generated by applying on $|00\rangle$ the unitary gate
\begin{equation}
V \equiv a_{00}(\mathbb{I}\otimes\mathbb{I}) + a_{01}(\mathbb{I}\otimes\sigma_x^{(B)})+a_{10}(\sigma_x^{(A)}\otimes\mathbb{I})+a_{11}(\sigma_x^{(A)}\otimes \sigma_x^{(B)})
\end{equation}
with $a_{ij}\in\mathbb{C}$, in general. By following Ref.\,\cite{ShendePRA2004}, it is found that $V$ can be implemented by means of just local  gates, so that the initial state $\rho_{\rm i}$ is separable.

In the experiments we have performed, the initial state $|\psi_{\rm i}\rangle$ is chosen so that $\phi_{k\ell}=0\,\forall{k,\ell}$ and it can be obtained by applying two identical single-qubit rotations
\begin{equation}
\label{rot}
U(\theta_0)\equiv\left(
\begin{array}{cc}
 \cos \left(\frac{\theta_0}{2}\right) &  -\sin \left(\frac{\theta }{2}\right) \\
  \sin \left(\frac{\theta_0 }{2}\right) & \cos \left(\frac{\theta }{2}\right)  \\
\end{array}
\right)
\end{equation}
with the rotation angle $\theta_0$ that must be chosen depending on the value of the inverse temperature $\beta$ and the frequency $\epsilon$.
More explicitly
\begin{equation}
  \text{sech}(\beta) =  \sin(\theta_0),
\end{equation}
in units of $\epsilon^{-1}$. Eq.~\eqref{rot} is routinely implemented in the IBMQ quantum computer. Given the separable nature of the initial state chosen for the experiments, here we are not investigating the role of the initial entanglement in the energetics of the process but we have limited ourselves to investigate the role of the initial coherence in the computational basis. We leave the investigation of the role of entanglement for future works.

\subsection{Two-qubit gates}

After initialization, the experiments proceed with two initial projective measurements for the TPM scheme and no measurement for the EPM protocol. Afterwards, as shown in the top panel of Fig.\,2 in the main manuscript, the circuit implements a controlled gate, followed by
a final energy measurement in the computational basis of the two-qubits. The controlled unitary reads
\begin{equation}
|0\rangle\!\langle0|_A\otimes\mathbb{ I}^{(B)}+|1\rangle\!\langle1|_A\otimes U^{(B)}(\theta,\phi,\lambda)
\end{equation}
with $U(\theta,\phi,\lambda)$ the
standard $U$-gate provided by IBMQ, i.e.,
\begin{equation}
U^{(B)}(\theta,\phi,\lambda)\equiv\left(
\begin{array}{cc}
 \cos \left(\frac{\theta }{2}\right) & -\exp (i \lambda ) \sin \left(\frac{\theta }{2}\right) \\
 \exp (i \phi ) \sin \left(\frac{\theta }{2}\right) & \cos \left(\frac{\theta }{2}\right) \exp (i (\lambda +\phi )) \\
\end{array}
\right)
\end{equation}
that generalizes the rotation used for the preparation of the initial state of the computer. In our experiments, we have used $U(\theta_n,0,0)$, where $\theta_n$ varies from zero to $2\pi$ in steps of $\pi/10$.

\subsection{Additional experimental results}

In this subsection we report additional results with respect to what was shown in the main text. In particular, we focus our attention on the experimental values of the energy change statistical moments. We also show how the behaviour of the experimental data is well captured by working at the liner response level for what concerns the characteristic functions.
In other terms, we observe that the expressions for the characteristic functions of the energy change distribution can be expanded as a function of few statistical moments (just two suffice) with a negligible error. This allows us to just consider the experimental data of the first and second statistical moments of the energy-change distribution to properly describe the energetics of the quantum circuits at hand.

For completeness, we report the analytical expressions
of the energy-chance characteristic functions for an initial pure state of the form $\rho_{\rm i}=\rho^{\rm th}+\chi$, with all the phases in Eq.~\eqref{phases} vanishing. We have
\begin{align}
    &\mathcal{G}_{\rm TPM}(i\beta)=1,\\
    &\mathcal{G}_{\rm EPM}(i\beta)=\frac{4 \left(e^{6 \beta  \epsilon } \left(\sin (2 \theta )-e^{\beta  \epsilon } \cos (2 \theta )\right)^2+e^{4 \beta  \epsilon } \left(e^{\beta  \epsilon } \sin (2 \theta )+\cos (2 \theta )\right)^2+e^{4 \beta  \epsilon }+1\right)}{\left(e^{2 \beta  \epsilon }+1\right)^4},\\
    &\mathcal{G}_{\rm EPM}^{(\rm{diag})}(i\beta)=\frac{4 \left(2 e^{6 \beta  \epsilon } \sin ^2(2 \theta )+\left(e^{4 \beta  \epsilon }+e^{8 \beta  \epsilon }\right) \cos ^2(2 \theta )+e^{4 \beta  \epsilon }+1\right)}{\left(e^{2 \beta  \epsilon }+1\right)^4},\\
    &\mathcal{G}_{\rm EPM}^{(\rm{coh})}(i\beta)=-\frac{1}{2} e^{2 \beta  \epsilon } \sin (4 \theta ) \tanh (\beta  \epsilon ) \text{sech}^3(\beta  \epsilon )\,.
\end{align}
In Fig.~\ref{LR}, we show how considering only up to the third moment of the probability distributions reproduces the main features of  each characteristic function. This leads us to investigate the first moments explicitly, also at the experimental level. The results of this analysis are reported in Fig.~\ref{first} in which we show the first four statistical moments of the energy change probability distributions obtained by applying both the TPM and EMP protocols. In particular, Fig.~\ref{first} shows the comparison of the experimental data for the first to the fourth moments with the analytical curves.

Panels \textbf{(b-d)}: same as before but for the second, third and fourth moments.}
\label{first}
\end{figure*}

It is worth noticing the growing discrepancy between the analytical results and the experimental ones for higher moments of the probability distributions. In particular, the EPM statistics seems to be particularly affected by this. We can link this effect to the idealization of the system as completely unitary in the theoretical calculations with respect to the actual IBMQ architecture.

\section{Further application: Three-level system in contact with thermal baths}

In order to showcase once more the effect of initial coherence singled out by our EPM protocol, in this section we address an archetypal quantum thermal machine (see also Refs.~\cite{ScovilPRL59,PalaoPRE2001,KosloffARPC2014}), i.e. a three-level quantum system interacting with thermal reservoirs and driven by a time-dependent Hamiltonian, as shown in Fig.~\ref{newfig} \textbf{(a)}. In contrast with the actual experiments presented in the main text, this example is a numerical exercise which, however, considers a relevant system for quantum thermodynamic considerations and allows us to address in more detail the entropic consequences of adopting the EPM. Furthermore, we also explicitly confront the predictions of the EPM protocol with the ones that can be obtained from the MLL one.

The dynamics of the system is described by
the master equation
\begin{equation}\label{me3main}
  \dot{\rho} = -i[H_{\rm t},\rho] + \sum_{i\neq j=1}^{3} \left(L_{ij}\rho L_{ij}^{\dag} - \frac{1}{2}\{L_{ij}^{\dag} L_{ij},\rho\}\right).
\end{equation}
Here, $L_{ij}\equiv\sqrt{\eta_{ij}}|\epsilon_i\rangle\!\langle \epsilon_j|$
is a jump operator acting at rate
$\eta_{ij}$ with
\begin{equation}
\begin{aligned}
    & \eta_{gA}=\gamma\,(n_1^{th}+1), \quad \eta_{Ag}=\gamma\,n_1^{th}, \quad \eta_{AB}=\gamma\,(n_2^{th}+1),\\
    & \eta_{BA}=\gamma\,n_2^{th}, \quad \eta_{gB}=\gamma\,(n_3^{th}+1), \quad \eta_{Bg}=\gamma\,n_3^{th}
\end{aligned}
\end{equation}
where $n_r^{\rm th}=(e^{\beta_r\omega_r}+1)^{-1}$ and {$\omega_2=\omega_3-\omega_1$}.
The Hamiltonian of the system can be written as $H_{\rm t}=H+H_{\rm{drive}}(t)$ where the free-system Hamiltonian is given by
\begin{equation}
    H=\omega_3|\epsilon_B\rangle\!\langle\epsilon_B|+\omega_1 |\epsilon_A\rangle\!\langle\epsilon_A|
\end{equation}
with its eigensystem $\{\ket{\epsilon_g},\ket{\epsilon_A},\ket{\epsilon_B};0,\omega_1,\omega_3\}$, while the external driving term is represented by the following time-dependent Hamiltonian
\begin{equation}\label{SMdrive}
    H_{\rm{drive}}(t)=g(t)(|\epsilon_g\rangle\!\langle\epsilon_B|+{\rm h.c.})+f(t)(|\epsilon_A\rangle\!\langle\epsilon_B|+{\rm h.c.})
\end{equation}
that drives the transitions between the second excited state and both the ground and first-excited states with $f(t)$ and $g(t)$ time-dependent rates.

Note that, for reservoirs at the same temperature and $H_{\rm drive}=0$, the system relaxes to $\rho^\text{th}_{\infty} \equiv e^{-\beta H}/{\rm Tr}(e^{-\beta H})$: independently of $\rho_{\rm i}$, the distribution of the EPM scheme converges to the one resulting from MLL and TPM. This holds for any map with a unique fixed-point. Differently, at finite times the statistics from the three approaches differ even for no coherence in $\rho_{\rm i}$.

We first address the unitary case, i.e., when the three-level system is decoupled from the thermal reservoirs. In this case, the TPM protocol leads to the Jarzynski equality $\langle e^{-\beta(\Delta E-\Delta F)}\rangle=1$. This is compared to the contribution in Eq.~\eqref{eqJarSI} (Eq.(8) of the main text)
linked to the diagonal and off-diagonal parts of the initial state $\rho_{\rm i}$ in Fig.~\ref{newfig} {\bf (b)}.

A similar comparison can be done in the case of open quantum system dynamics, when the system interact with the thermal reservoirs. In Fig.~\ref{newfig2}, we consider the deviation of $\langle e^{-\beta(\Delta E-\Delta F)}\rangle_{\rm EPM}$ from the result of the TPM scheme, as encoded in Eq.~\eqref{eqJarSI} (namely Eq.~(8) of the main text), and we also plot the two contributions on the right hand side of Eq.~\eqref{eqJarSI} linked to the diagonal and off-diagonal parts of the initial state $\rho_{\rm i}$ respectively. Note that in this case, also the TPM result differ from unity being the open system dynamics neither unitary nor unital.

The dash-dotted orange curve represents the contribution depending only on the initial quantum coherence brought forward by $\rho_{\rm i}$. Note that, in obtaining these curves, the driving term in Eq.~\eqref{SMdrive} has been included and the initial state as been chosen as $\rho_{\rm i}=\exp{\left(-\beta H(t_{\rm i})\right)/Z_{\rm i}+\chi}$ with $\beta=0.5$ and $\chi$ being randomly generated, but such that $\rho_{\rm i}$ is a legitimate physical state.}

\label{fig:2nd_moment_coh}
\end{figure}
Fig.~\ref{fig:2nd_moment_coh} shows the temporal behavior of $1 - \langle\Delta E^2\rangle_{\mathcal{P}}/\langle\Delta E^2\rangle$,
evaluated using Eq.~(6) of the main text an
~\eqref{me3main}, thus addressing the contribution
to the $2^\text{nd}$ moment of $\Delta E$ originated by the
initial-coherence terms in $\rho_{\rm i}$. In this case, the contribution of the initial coherence is $\sim40\%$
of the value taken by the $2^\text{nd}$ energy moment. However, while the initial coherences impact significantly on the stochastic energetics, the time behavior of $\langle\Delta E^2\rangle - \langle\Delta E^2\rangle_{\mathcal{P}}$ is not monotonic with the amount of such coherences (as quantified by the measure of quantum coherence $C_{L1} \equiv \frac{1}{2}\sum_{i\neq j}|\rho_{ij}|$~\cite{Baumgratz}).

In Fig.~\ref{fig:2nd_moment_cohSI} we show the discrepancies between the Shannon entropy of the EPM-based energy change probability distribution in the absence of initial coherence and the one stemming from
TPM-based predictions. As discussed in the main text, this difference quantifies the extra uncertainty, with respect to the TPM scheme, due to not performing the initial energy measurement. Finally, the inset of Fig.~\ref{fig:2nd_moment_cohSI} shows how coherences in the initial state can make the entropy difference negative. This implies that initial coherence could compensate for the extra-uncertainty due to the virtual initial measurement, thus providing a statistically more informative characterisation of energy fluctuations.

From these results, we deduce that the quantum coherence initially present in $\rho_{\rm i}$ (in the system energy basis) has an active role in the first part of the system evolution and is propagated thanks to the action of the driving Hamiltonian. This phenomenon is well-captured by the energy change fluctuations quantified by the EPM protocol. In this specific example, the contribution of the coherence is suppressed at long times. This is due to the fact that the dynamics reaches a (time-dependent) fixed-point, independently of the initial state. Consistently with our previous discussion, in this scenario the EPM probability distribution converges to the TPM one. It should also be noted that, while the initial coherence has a relevant impact on the statistics of the energy fluctuations, also for the Shannon entropy no monotonic relation with the initial coherence is present, as shown in Fig.\,\ref{fig:2nd_moment_cohSI}. The curves corresponding to initial states with maximum coherence never maximize the difference between the results from EPM and TPM distributions, even though they are rather close to it.

Inset: Difference between the Shannon entropies for the full, non-diagonal, density matrices $\rho_{\rm i}$. In both figures, the blue-shaded regions encompass the values obtained by numerically evaluating the statistics of $\Delta E$ for $10^3$ random initial states --- uniformly sampled by respecting the Haar measure of the space of $3\times 3$ density operators. The red solid lines (black dash-dotted line) denote the corresponding curves obtained by taking in such sample the initial quantum state with the lowest (highest) value of coherence according to the quantum coherence measure $C_{L1}$ as in Ref.~\cite{Baumgratz}. The parameters used in the simulations are $\omega_k = k\omega_1$, $\gamma=0.1\omega_1$, $\beta_1=3$, $\beta_2=1$, $\beta_3=2$, $g(t)=1.5\sin^2(t)$ and $f(t)=1.5(1-\sin^2(2t))$ with  $\omega_1 = \hbar = k_B = 1$.}

\end{figure*}

Finally, the dynamics of the open quantum system without the external driving and with possibly different temperatures describes processes involving only heat exchanges which are the main focus of Ref.~\cite{Micadei_SM}. Thus, we also explore this case in order to highlight some of the differences between the EPM protocol and the MLL scheme.
\begin{figure}[t]
\centering
\includegraphics[width=0.55\textwidth]{secondmomentsdiff.pdf
\caption{Difference between the second moment of
  the MLL probability distribution and the one from the EPM protocol for 100 randomly sampled initial states. The shaded area comprises all the differences, as a function of time, for each initial state. It can be easily seen that only seldom the second moment of the MLL scheme results bigger than the one of the EPM scheme. It should be noted that, asymptotically the difference vanishes. The inset shows that the coherence contribution to the second moment of the EPM distribution $\langle\Delta E^2\rangle_\chi$
  is, in this case, negligible throughout the dynamics. The dashed black curve {corresponds to} one instance for a randomly picked initial state. We have used $\omega_k = k\omega_1$, $\gamma=0.1\omega_1$, $\beta_1=3$, $\beta_2=1$, $\beta_3=2$, $g(t)=1.5\sin^2(t)$ and $f(t)=1.5-g(t)$ with  $\hbar = k_B = 1$. }
  \label{figsec}
\end{figure}
In Fig.~\ref{figsec}, we show the difference between the second moments of the MLL and the present EPM protocol probability distributions, as a function of time and for 100 randomly chosen initial state. The inset shows that the coherence contribution is negligible. It is easy to see that, for the vast majority of cases, the second moment from the EPM protocol is greater than the one of the MLL scheme. When this happens, we can already conclude that, in the EPM protocol, we need to pay the freedom deriving from not performing any initial measurements with an increase in the uncertainty of the probability distribution. In the few cases, and instants of time, in which the hierarchy of the second moments is reversed, we need to resort to a more refined notion of uncertainty.
\begin{figure}[t
\centering
\includegraphics[width=0.55\textwidth]{ShannonDiffV2.pdf}
\caption{Difference between the Shannon entropy of the EPM protocol probability distribution and the one of the MLL scheme for 100 randomly sampled initial states. The shaded area comprises all the differences, as a function of time, for each initial state. Instead, the inset shows the difference between the Shannon entropy of the EPM protocol probability distribution and the one of the TPM scheme for the same 100 randomly sampled initial states. The dashed red curve corresponds to an instance of the differences for a randomly picked initial state. It should be noted that, asymptotically, the difference vanishes (colors online).}
  \label{figentr}
\end{figure}
We do so in Fig.~\ref{figentr}, where it is shown the difference between the Shannon entropy $\mathcal{H}$ of the EPM protocol probability distribution with the one of the MLL and TPM schemes, for the same random sampling of 100 initial states as before. We see that the Shannon entropy of the EPM protocol is always greater than the one of the other schemes, which proves the increase of uncertainty due to the initial virtual measurement. While this result is expected for the comparison between the EPM and MLL schemes, as discussed before, the comparison with the TPM scheme is consistent with the fact that the effect of the initial coherence is negligible in this case. Finally, it should be noted that both the differences of second moments and Shannon entropies vanish at long times, consistently with the fact that the system reaches asymptotically a (non-equilibrium) steady-state, where all the probability distributions introduced before coincide.

I bought myself a Surface Go (8Gb/128Gb) a few weeks ago, and I've had it long enough now to pass judgment.
As I noted in my 'hardware I use' post, I was previously using a Surface Pro 3, until I sadly dropped it on the hard floor after a lecture. To be honest, I'd been considering changing up for a while; the Pro was a few years old but it wasn't the performance that was the problem. Having a work computer and a home desktop meant that I didn't need a huge amount of power on the go in between (on the train to work, or when travelling to conferences etc). I really wanted to use the Surface Pro 3 for reading and note-taking, as well as giving lectures, but I was finding it was ever so slightly on the large side for comfortably reading a paper or taking notes in a meeting.
So when the Surface Go was announced, I was intrigued. While the Surface Pro (v3 onwards) has a 12" screen, the Surface Go has a 10" screen, so it's just a bit smaller. I went for the 8Gb Ram, 128Gb ssd version (the other version has 4Gb of Ram and 64Gb ssd). I managed to pick one up from Amazon for £417, which was the best part of £80 less than it was direct from the Microsoft store. I also grabbed a burgundy type cover from Amazon for £80, rather than the £125 that they cost from Microsoft. Both were brand new, sealed, and in excellent condition (Prices at the links above will vary based on sellers' availability). I also replaced my old 2016 Pen (4th Gen) with the latest that supports tilt, buying a used one from CEX.
The new Surface Go on the left, and my old, injured, Surface Pro 3 (with Pro 4 type cover) on the right). There's only 2″ difference in screen size, but they do feel and look substantially different sizes.
The Surface go comes with Windows 10 Home in S-mode. If you're not familiar, this is a more restricted version of Windows 10 that only allows installation of apps from the windows store. I'm torn on this. On the one hand, I use the store whenever I can – installation and uninstallation are so much easier, and having programs kept up to date in the background is brilliant. But, there's always that one program you need that's not in the store. In my case, that's a range of softwares: Photoshop, Maya, Matlab, Endnote…. Luckily turning off S-mode is really easy, and took just a couple of minutes. I was then happy to install those core programs and turn S-mode on (well, restrict installations to store-apps only), because frankly it just makes the device a little more secure. Hopefully one day everything I need will be in the Windows store and I won't need to do this.
I was also a bit worried about it being windows 10 home and not Pro. The main differentiators for me are bitlocker and connecting to the device via remote desktop. The former is encryption on the harddrive, and it's most vital for portable, mobile devices like this. Thankfully, the Go does utilize bitlocker even though it's Windows 10 Home. Remote desktop is a nicety, but frankly apps like Team Viewer do a better job anyway, and now it's been pointed out to me, it would be rare I'd be remoting into the surface Go, rather than the other way around. You'd also need Win 10 pro to use Hyper-V, the virtualization technology, but let's be honest: you probably don't want to be running virtual machines on this thing.
As with all surface devices, the build quality really is excellent. Fit and finish never feel less than premium. I do have a little light bleed on the bottom edge of the device, but it's not noticeable when the taskbar is there in desktop mode, and it's not noticeable in portrait when I'm reading PDFs with a white background, either. Mildly annoying, but not a deal breaker (and it may be the reason my device was £80 less than RRP).
Now, the reason that it took a big crack running across my Pro 3's screen to push me to make the jump is because I'm finding with a lot of devices these days that the performance/portability trade off is an incredibly difficult compromise for me to make. The work I do, namely high performance simulations, photogrammetry, 3D modelling, and rendering, generally takes a lot of power. But every step towards more portability is a step away from performance. The Pro 3 I'd been using had 4gb of Ram, 128 Gb storage, and an i5 processor. The i5 was good, but not super powerful, and while I could just about render small animations in Maya, and process data, it took a while.
The move to a Surface Go was something of a sideways transition – the version I bought has double the Ram, but the processor, a Y-series 4415Y (dual core 1.6GHz) is about on par with the i5 in the Pro 3. It's no powerhouse, but it can absolutely run photoshop, or Maya, and render out some videos if I need to when travelling. To give you another idea of performance (if you're into gaming): I've been playing Divinity Original Sin 2 with my wife, and I chivalrously let her use the Surface Go while I use my Desktop. But the little machine can handle this modern game on low settings (and medium textures) surprisingly well!
Here's the Surface GO running a simple Maya scene, impressively running the IPR Arnold Renderer in the top right view.
But… and this is something I didn't fully appreciate before I pulled the trigger: the size is fantastic. Those 2" really make a difference (*ahem*). The screen is a 3:2 ratio, 1800×1200 resolution, and looks absolutely fantastic. but unlike the Pro 3, it's small enough to comfortably hold in one hand, in portrait mode, reading a PDF. It's not a world of difference in size, but the feeling of getting it out to read a paper on the train is substantially better than pulling out the larger, heavier, surface pro. My Pro was a few generations old, and I know the newer Pros have an improved design, but the more rounded corners of the Go also make it far more comfortable to hold than the Pro 3 ever was.
The size does mean that the type cover is a little smaller than I was used to on the Surface Pro, but the keys are excellent, and the Alcantara covering feels really premium. As a matter of principle, I switched here from writing this post on my desktop to writing it on the Surface Go, and my speed of typing has barely changed, and I'm not seeing many more mistakes. To test this, I went to typingtest.com and tried to touch type with both the Surface Go and my desktop (with a Microsoft Designer Keyboard): On the Surface Go I got 51 words per minute with 7 mistakes, while on the desktop I got 56 words per minute with 1 mistake. My mistakes on the Go were mostly associated with needing to press shift – I just don't seem to be hitting those keys as easily as on the larger keyboard. Luckily that's the kind of mistake Word autocorrects! I'm sure with a little more practice and writing on the Go, I'll improve that significantly.
The SSD is fast, and the extra Ram gives me a little more breathing room than I had on the Pro 3. I wouldn't want to go down to the 64Gb SSD because after windows is installed, it doesn't leave a lot of space, and by all accounts the smaller SSD is also slower than that in the 128GB model.
This is the first device I've had with the Face-recognizing Windows Hello, and while the reviews I'd read told me it was fast, I didn't expect it to be this fast. Honestly, it's an unbelievably convenient way to sign into a device – I find it quicker and more reliable that the fingerprint reader on my Samsung Galaxy Note 8, and it's obviously far quicker than entering a password or Pin.
The performance is absolutely plenty for running PowerPoint slideshows, including embedded 1080p videos, and clicking links to content-heavy websites. On top of that, you can use the pen to ink directly on the screen, annotating images and text, or using blank slides as digital whiteboards. This has been really useful during my lectures.
In order to hook up the Surface Go you'll sadly need a dongle. The device is pretty limited with ports: there's a USB-C port, which can be used for peripherals (including display-out) as well as for charging, there's the awesome magnetic surface-connect charging port, and there's a 3.5 mm headphone jack. In order to be prepared for every eventualality, I picked up this dongle from Amazon for ~£20 that can handle VGA, DVI, HDMI, and supplies a USB-A port. So I can rock up to a lecture with just my small surface, hook it up to the VGA or HDMI cables, and I'm good to go.
The one downside is Battery Life. The Go isn't bad, but you're looking at about 4-5 hours of battery life. I can get a couple of two hour lectures out of it without charging, but I wouldn't want to go for a third without a charger handy. The USB-C charging is good, meaning I can hook up to a generic cable over lunch, but charging this way is slower than using the surface-connect port, and annoyingly if you're using the USB-C port for display out, you have to use the surface charger, and that means carrying more crap around, defeating the point of having such a portable device.
My work bag – Surface Go, Microsoft Arc Touch Mouse (old version), 2017 Surface Pen, USB-C dongle for video out (and USB-A), and a USB-C cable for a little charging top-up occasionally. These are all packed in my nice Waterfield Designs Surface Pro Satchel.
Obviously, the Surface Go can handle writing manuscripts and simple figure making as well as any computer (better, I'd argue, given the touch and pen capabilities in the recent versions of Office), but can you do anything more demanding on it? The answer is… yes, but you'll really want to make sure your workflow is set up so that you don't need constant high power. To that end, I make a lot of use of two tools: Windows Subsystem for Linux, which is probably the most significant improvement to Windows in a decade, and Team Viewer. The former means I can not only run linux programs locally (usually running test scenarios in my simulation software), but SSH and other such tools can be used natively to connect to supercomputers like ARCHER and run massively parallel simulations. I can visualise and analyse data pretty well on the machine itself, but for heavier tasks I use Team Viewer to remote into my home desktop and set-up large simulations or photogrammetry projects. I know it's faint praise, but being able to use the Go to easily connect to other computers, whatever their operating system, provides the power that would otherwise be missing from a small portable computer.
Where the Go does excel is in writing and reading papers. My commute involves a 30 minute train ride each way, and being able to pull out the device to read – and annotate – PDFs is great. I can write papers or respond to emails easily; short responses and notes can be accomplished easily with the on-screen keyboard or pen, but for longer pieces of text I just pull the keyboard around and start typing away. Thankfully the keys are much quieter than the terrible butterfly keyboards on the new MacBooks.
While the device gets a lot of attention for work-related stuff, it is a personal device and so gets used about the house for normal-people things. Watching movies, browsing reddit/twitter, and reading RSS feeds. Windows 10 offers some really nice apps in the store for these tasks, that make touch or keyboard comfortable to use. My wife and I tend to watch programs/movies on the Go, and certainly the smaller screen than the Pro 3 isn't great, but moving from room to room while listening to music is much better (the speakers are surprisingly good for such a small device).
I'd definitely struggle if the Surface Go was my only device. But having a decent computer at work and a desktop at home, I have no problem relying on this handy little fella while I'm out and about. I'll happily attend a week-long conference with only the Go, using it to take notes during talks, as well as render video and construct PowerPoints if I'm presenting myself (not that I'd be putting a presentation together at the last minute or anything…). As a device to commute with, I don't think there's any comparison out there – the portability is phenomenal, but at a moment's notice I can write a manuscript using EndNote, or work with a 3D scene in Maya, or process RAW images in photoshop. I love being able to give all my lectures from it, use it to read books and papers, write manuscripts and even process data on the go. Full windows in a package this small and capable is really something wonderful. It's a nearly perfect companion device.
Great review, thanks! Awaiting my LTE Surface Go and was pleased to read about your experience. As a fellow academic, I am curious about which Windows productivity apps you are using for your work. I am coming from Linux and looking for Windows replacements for some of my core tools.
Office is the first thing I install. I do so from the windows store so I only get what I need (Word, PowerPoint, excel, and Access). Onenote comes preinstalled and is invaluable. I put endnote on there for reference management.
For RSS I use nextgen reader, and poki as a pocket client.
ReddPlanet is an excellent reddit client.
I usually install photoshop and illustrator, but I've been using krita and inkscape (both in the store) and doing just fine.
This is terrific, thank you for these. I am still awaiting my Surface Go, but I will try all of these once I get it. I use Zotero as my reference manager, so I need a desktop word processor to get that working. I use LibreOffice, but it's nice to know that I can get the mobile MS Office apps working (or the full-fledged Office 365). I will definitely use Xodo for PDF because I use that extensively on my Android phone. That's a great tip there.
I'm also curious about Android virtualization to see if that could fill in some of the mobile app gaps in the Windows Store. I'll have to see how that works with a relatively low-power processor like the Pentium. I'll leave another post about my success or failure there!

I became fascinated by infectious diseases during my undergraduate degree (BSc Biology with Oceanography, University of Southampton, 1994), and I developed these interests further in a developing country context at the Liverpool School of Tropical Medicine (MSc Applied Parasitology & Medical Entomology, 1995). I returned to Southampton for my PhD studies on innate immunity in sexually-transmitted bacterial infections of humans, graduating in 2000. Following a brief postdoctoral position on meningococcal meningitis, I returned to Liverpool as a postdoc. in the research group of Prof. Alexander (Sandy) Trees, where I worked on the immunology and chemotherapy of onchocerciasis (River Blindness) in Cameroon, using the cattle model, Onchocerca ochengi. I was appointed to a proleptic lectureship position in the Institute of Infection & Global Health in May 2011.

Anyone can do yoga. It doesn't matter if you're inflexible, out of shape or have never done yoga. What matters is how fully engaged you are in each experience as you practice.
Far more than just a form of exercise, the "authentic" yoga takes you into states of consciousness which activates an inner dimension of harmony and well-being. In this place of integration, you learn to dismantle reactions and self-criticisms on a yoga mat and are then able to use that understanding to interact with your life off the mat in a new way. You cultivate more confidence and an improved connection to good health, personal talents and purpose.
1.	Let go of all preconceived notions about what yoga is. The popular trend of yoga as exercise is limiting. Yoga is not merely about practicing yoga poses (called "asanas). It's about freeing yourself physically, mentally and emotionally from all that may be holding you back in your life. When poses are practiced regularly with intention, yoga is a way of accessing who you truly are. It goes beyond fitness. It is an integration of mind, body heart and spirit that can accelerate happiness and fulfillment. Yoga poses are tools to ignite your personal power within. Many beginners never get introduced to this understanding and often abandon yoga all too quickly. They miss the miraculous life-changing benefits. I encourage you to explore the adventure with an open mind and heart.
2.	Get connected to this moment.
Begin in a seated position. Sit on the floor or in a chair. Close your eyes. Notice feelings in your body. How does the floor or chair feel beneath you? Focus on your breathing; inhaling and exhaling--a natural function that animates body and mind. Deepen your next inhalation and on the exhalation, open your mouth and express the sound of OM, emptying your lungs. Notice how the vibrations feel on your lips and in your body. Repeat the sound two more times allowing yourself to let go into the tones. Next resume your normal breathing. You've just practiced awareness and a sense of integration. This is a helpful start towards getting present and becoming centered. Were you thinking about what you're having for dinner later or worrying about something that may or may not happen tomorrow? I hope you stayed focused and committed to your experience.
3.	Become the observer when you practice.
In the yoga of consciousness that I teach (known as IAM Yoga--Integrative Amrit Method from world-renowned yogi master Amrit Desai), there are two parts to every pose. The first is the traditional Hatha Yoga and presents the active, dynamic pose. The second is Raja Yoga, a pause to feel the internal effects of the physical movement and enter deep silence. By combining the two, you connect to the observer where you watch your thoughts and reactions without judgment.
Your ego wants to criticize with a constant chatter of comments like: "I'm no good." "I didn't do that right." Accept that you are not your ego or your thoughts. You are the witness, the watcher of those thoughts and emotions.
•	Stand tall with your feet shoulder width apart. Bring your palms together in front of your heart.
•	Press your feet into the ground and extend your arms up over your head.
•	Look straight ahead. Interlace index fingers and point toward the sky. Your chin is parallel to the floor. Relax your shoulders. Breathe.
•	Become the observer by feeling sensations in your body; your shoulders, arms. Direct your attention to the energetic press points by dropping your tailbone, firm through the buttocks and inner thighs as you press into the feet, extend up through the spine and out through the fingers. Relax the shoulders slightly. Breathe several slow, uniform breaths. The channels and meridians in your entire body are opening. Notice all sensations. Resist the urge to think about what's next or if you're doing it perfectly. Just keep focused on feelings, on energies.
•	To release: lower your hands in prayer position in front of your chest.
•	Relax your arms at your sides.
•	Close your eyes. Breathe normally. Give your undivided attention to the released energy as it appears to you in the form of sensations in your body. Experience totally the energy field that is actively expanding and spreading throughout.
The practice of yoga poses shows you how to calm the restless mind by focusing on feeling and being. It teaches how to accept whatever is showing up in any given moment. When you truly integrate mind and body in your yoga practice, you enter a deeper level that allows you to use your body to connect to the divinity within. In this way, you align with your higher self and can effortlessly find your path to wellness, passion and purpose.
Well explained, Yoga is a physical and mental practice that helps you to stay fit, healthy and happy. It also helps you to reduce body and joint pain. But before starting yoga, make an appointment with yoga trainer. Thanks.
Thank you, Michele. Good comment and advice!

This is supposed to print all numbers that have number 7, but what if I want the number that contains exactly one 7?

A: Here is one approach:
for each d count the number of 7s, and select the ones that contain exactly one. (thanks @MrXcoder for the assist in the comments)
from itertools import product
for d in product(range(10), repeat=4):
    if d.count(7) == 1:
        print(d)

Taken in Toronto just off of Dufferin St. near Steeles St. I've had this picture in my collection for a while, it's one taken during one of the all night photo taking session I do with a good friend of mine. I found a lot of forgotten picture in this set that I like, so I'll have some fresh content for the next little while.
