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.

A Memory Powered Engine. Classical heat engines, such as petrol motors, convert thermal energy from hot gases into useful work, but with limited efficiency as much of the thermal energy is lost as waste heat. The project aims to combine experimental techniques in quantum information processing with recent theoretical developments in quantum thermodynamics to demonstrate a proof-of-concept heat engine that converts thermal energy into work with 100% efficiency.
