A Space-Based Quantum Communications Platform using Continuous Variables. This work proposes to investigate a new space-borne platform capable of quantum communications with a terrestrial ground station. Different from existing space-borne quantum communication platforms, our new platform will be based on CV (Continuous Variable) technology and will integrate the ability to seamlessly switch to classical Free-Space Optical communications when channel conditions deem quantum communications are too difficult. Currently no quantum satellite built on CV technology exists. Our research will produce a significant advance in an emerging technology space, and will allow Australia to take scientific leadership in an important aspect of ultra-secure communications from satellites.

This project aims to implement a quantum computer memory module which can be integrated in a future hybrid quantum computer, where the advantages of different quantum platforms are combined. The memory module will be achieved by coupling a superconducting qubit to the surface vibrations of superfluid helium and exchanging quantum information between the qubit and helium. By simulating chemical reactions, the project expects to find cleaner alternatives of current industrial processes, reducing environmental impact. The outcomes should provide significant benefits for testing the validity of quantum mechanics, and by contributing to the realisation of a quantum computer, contribute to broad socio-economic benefits.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. 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
