Quantum phenomena are ubiquitous and critical to the functioning of many modern technological devices, for example sensors and computer chips used in mobile phones. Although great strides have been made in recent decades in describing quantum phenomena theoretically, computational modelling is an essential ingredient to describe real experiments and devices. This project aims to develop the next generation of computational tools aimed at two major themes: characterising topological states of matter, and modelling non-equilibrium phenomena. These tools will be invaluable for the design and modelling of quantum devices and novel materials and will enable the development of the next generation of technological devices.Read moreRead less
Storage of non-classical light in a solid. A new scheme for storing and recalling coherent light pulses based on 'slow light' has been demonstrated. The aim of this project is to show how this can best be achieved in a solid to enable practical applications. A range of materials will be investigated. The novel feature of the storage is the maintenace of the coherence information and a noise analysis will be made to determine whether it is experimentally possible to store non-classical light.
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
