The project aims to design and build a revolutionary new type of laser based on the ground-breaking 2020 Nature Physics paper by the two Chief Investigators. 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

Emergent many-body phenomena in engineered quantum optical systems. In recent years, scientists have realised unprecedented control over light-matter interaction. Single particle dynamics in engineered systems are now well understood, but when scaled up, the many-body behaviour remains unexplored.

In recent years, scientists have realised unprecedented control over light-matter interaction. Single particle dynamics in engineered systems are now well understood, but when scaled up, the many-body behaviour remains unexplored. This project will significantly advance our understanding of new emergent quantum phenomena arising from engineered interactions between many particles. These phenomena are qualitatively new behaviour that cannot be explained as an extension of single-particle behaviour. The chief aim is to unravel the quantum dynamics of these systems. The project is expected to assist in producing new quantum technologies such as sources and detectors of quantum light and new atomic clocks.

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. Further, the theory of nonlocality in multiparty networks is almost completely undeveloped. The project’s anticipated outcomes are novel experiment and theory to bypass bar ....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. 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
