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 design and develop low-cost reconfigurable end-user antennas that could be integrated with low-earth-orbit satellites so regional and remote Australians can access broadband. While broadband is taking its place alongside water and electricity as essential infrastructure, people in regional Australia lack genuine broadband services. These antennas are expected to give these communities reliable access to e-health services and distance education, and make their businesses more productive with access to new markets. The proposed antennas should also make broadband services available in the air, at sea, or on the move.Read moreRead less

The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less

Tools and models for measuring and predicting growth in internet addressing and routing complexity. We analyse patterns in the allocation and actual use of Internet Protocol version 4 (IPv4) addresses to predict the technical and market pressures for deployment of IPv6. The utilisation models will help evaluate the potential for emerging markets in scarce IPv4 address prefixes to increase costs to the end-users of Australia's future national broadband network.
Next-Generation Solvers for Complex Microwave Engineering Problems. This project aims to design a complementary physics-guided, data-driven method that can accurately solve complex microwave engineering problems in a timely manner. The primary bottleneck so far preventing that approach, which is the disparity between the trained theoretical model and reality, will be overcome using a multi-frequency complex-valued domain adaptation technique.
