Integrated quantum photonics
As the field has progressed new quantum algorithms have been developed which provide short and long term routes towards the demonstration of the superiority of quantum computers over their classical counterparts. Cluster state computation is now generally accepted as the approach that will be used to develop a fully fledged quantum computer. Whilst development of quantum computer will require the synthesis of many different aspects of integrated optics, boson sampling seeks to demonstrate the power of quantum computation via technologies readily available and is therefore a very promising near term algorithm to doing so. In fact shortly after its proposal there were several small scale experimental demonstrations of the boson sampling algorithm

The "second quantum revolution", or "quantum 2.0" is a term that is often used to describe quantum technologies based on superposition and entanglement. Originally described in a 1997 book by Gerard J. Milburn, which was then followed by a 2003 article by Jonathan P. Dowling and Gerard J. Milburn, as well as a 2003 article by David Deutsch. These technologies use equipment such as highly stabilised laser systems, magneto-optical traps, cryogenic cooled solid state devices, ion traps and vacuum systems to create, manipulate and then use quantum effects for a number of different purposes. These include: quantum information processing, such as quantum computing, quantum simulation, quantum secure communications, quantum sensing and metrology and quantum imaging, and are widely believed to offer capabilities that will out-perform existing and future classical technologies.
