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.

Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory.

The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also applicable to microscopic systems. The expressions will determine the probability that finite sized systems will violate the Second Law for small periods of time and will therefore contribute to development of a fundamental understanding of microscopic systems and the development of nanotechnology.
