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.

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

Our understanding of quantum mechanics directly fuels new technology. We are on the verge of a new revolution in technology, where the aspects of quantum physics that we haven't been able to understand are now within technological reach. Our concept of solid-light joins two of the most important branches of physics, and in so doing develops a new technology of diamond-based quantum processors that will be built in Australia. This will benefit the Australian scientific community by providing devices to solve important quantum problems, and benefit the wider community by growing a new industry based around diamond quantum nanoscience.Read moreRead less
Detection and Control of Ultracold Atoms. Australia is at the forefront of research into atom lasers, a device that may be as important to science and technology this century as the laser was in the last. This project will provide important theoretical tools for developing the atom laser from an object of intrinsic interest to a useful tool. It will develop Australian scientific expertise in this area, and provide training for the next generation of Australian scientists.
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
