In quantum information theory there are the additional resources of entanglement and quantum communication. The aim of this project is to establish a complete theory of resources for quantum networks, by determining the relation between these resources, their symmetry properties, and effective ways of calculating capacities. Critical issues, such as the networking of quantum computers, quantum teleportation and secure communication, require a complete theory of resources. The expected outcome of this project is a rigorous foundation for resources in quantum information that may be used to address these issues.Read moreRead less

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.

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

The significance of this work is that it overturns 60 years of theory about the limits to laser coherence, by applying 21st century quantum theory and quantum technology to the problem. This project expects to greatly advance the theory and, by instigating a collaboration with world-leading experimentalists working with superconducting quantum devices, to demonstrate a laser with coherence beyond what was thought possible. Benefits of the project should flow from the manifold applications for highly coherent radiation, including scaling up superconducting quantum computing.Read moreRead less

Harnessing genuine quantum nonlocality. This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases.

This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases. Further, the theory of nonlocality in multiparty networks is almost completely undeveloped. The project’s anticipated outcomes are novel experiment and theory to bypass barriers and open up nonlocal network protocols. It is also expected to rigorously establish that a single-photon wavefunction after a beamsplitter is truly nonlocal. Likely future benefits include secure random numbers, secure distributed information technology and world-best photon sources.Read moreRead less
