Optical realisations of continuous-variable quantum information. The project aims to develop a framework for optical realisations of continuous-variable quantum information. Such realisations offer the potential for major technological advances in quantum information processing in the near future, but are currently impeded by the lack of a well-defined theoretical foundation. This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. ....Optical realisations of continuous-variable quantum information. The project aims to develop a framework for optical realisations of continuous-variable quantum information. Such realisations offer the potential for major technological advances in quantum information processing in the near future, but are currently impeded by the lack of a well-defined theoretical foundation. This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. Feasible experiments to test and exploit continuous-variable quantum information processing will be proposed. The resulting framework will allow the field to progress beyond proof-of-principle demonstrations and to develop new, technology-driven quantum information protocols.Read moreRead less
Novel aspects and applications of quantum measurement theory. The first aim is to develop further a novel formalism for quantum measurement theory based on retrodiction (rather than prediction). The second is to apply this theory to non-Markovian systems (in which the measurement is smeared-out in time). The third is to combine quantum measurement theory with natural selection better to understand the appearance of the everyday world. The expected outcomes include a deeper understanding of quant ....Novel aspects and applications of quantum measurement theory. The first aim is to develop further a novel formalism for quantum measurement theory based on retrodiction (rather than prediction). The second is to apply this theory to non-Markovian systems (in which the measurement is smeared-out in time). The third is to combine quantum measurement theory with natural selection better to understand the appearance of the everyday world. The expected outcomes include a deeper understanding of quantum physics and the establishment of new techniques for analysing problems in quantum communication and quantum-limited technologies. These advances are significant both fundamentally and, at the dawn of the quantum information age, in practice.Read moreRead less
Entanglement Processing in N-Atom Systems. An essential part of modern technological society is an understanding the scientific explanation of the world around us, and a realization that these explanations must be critically tested in the light of technological advances. The study of multi-atom entanglement is closely related to questions of fundamental physics. A breakthrough in stimulating this problem could have applications in other areas of physics and in technology, such as information pro ....Entanglement Processing in N-Atom Systems.

Quantum Atom Optics and Single Atom Detection with Micro-Bose-Einstein Condensates. A Bose Einstein condensate (BEC) is a collection of atoms, all in the same quantum state, like the photons in a laser. It is now possible to create a micro-BEC and move it around on an 'atom chip'. We propose an experimental and theoretical study of its properties including those quantum statistical effects which will limit future ultra-sensitive measurement technologies such as quantum electromechanical transdu ....Quantum Atom Optics and Single Atom Detection with Micro-Bose-Einstein Condensates.

When quantum is not desirable: quantum noise vs. quantum technologies. One of the key remaining obstacles to the successful deployment of quantum computers & sensors in science, industry, and society is the existence of noise sources that are themselves quantum, and thus have an unmatched potential for disruption.

One of the key remaining obstacles to the successful deployment of quantum computers & sensors in science, industry, and society is the existence of noise sources that are themselves quantum, and thus have an unmatched potential for disruption.
