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

This project aims to build a complete and scalable platform for the new paradigm of quantum acoustics, ready for immediate deployment as a critical component of a hybrid quantum computing architecture. Using a combination of theoretical techniques at the boundary of quantum physics, nanoscale electromagnetism, classical theory of elasticity, and advanced numerical methods, I will design a complete suite of quantum acoustic devices and protocols to enable interfacing between state-of-the-art quantum devices. This project will strengthen the leading position of Australian researchers in the race towards quantum technologies by offering practical solutions to a critical bottleneck in designing large-scale quantum technologies.Read moreRead less
Bulk-boundary correspondence in quantum many-body systems. This project will develop theoretical and numerical methods to explore how the bulk properties of quantum materials at low temperature are manifested on the edge of the material. Characterising this bulk-boundary correspondence will uncover new regimes of physics and underpin the development of powerful quantum technologies in the laboratory.
Foundation technology for quantum measurement, sensing and computing. This project will advance quantum control of cold ions, atoms and diamond colour centres for application of quantum science to high-tech problems, from ion-based quantum computing to diamond-based quantum imaging inside living cells.

Heisenberg-limited lasers: building the revolution. 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-leadin ....Heisenberg-limited lasers: building the revolution. 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
