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.

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

Heralded entangled photons to enable quantum networking and computation. This project aims to advance quantum networking and quantum computation by developing the science of new heralded, i.e. nondestructively verified, entangled states of photons. Despite great potential, photonic quantum technologies have been held back by the lack of key resources in the form of heralded entangled states of photons. Expected outcomes of the project include novel experimental capabilities of heralded state gen ....Heralded entangled photons to enable quantum networking and computation. This project aims to advance quantum networking and quantum computation by developing the science of new heralded, i.e. nondestructively verified, entangled states of photons. Despite great potential, photonic quantum technologies have been held back by the lack of key resources in the form of heralded entangled states of photons. Expected outcomes of the project include novel experimental capabilities of heralded state generation and powerful new theoretical methods for photonic circuit design. This should enable the realisation of quantum protocols with a genuine advantage, a critical step towards practical quantum technologies underlying the next generation of cybersecurity.Read moreRead less

Secure quantum computing in a distributed world. This project aims to design protocols for secure cloud quantum computing, where clients can license the use of a host’s computer, while keeping their data secure from both eavesdroppers and the host.

Quantum computers will transform the computational landscape of the 21st century, but will be affordable by few. Finding models for sharing quantum computing resources in a distributed environment is essential. Data security is important to clients – typical applications for quantum computing will involve commercially or strategically sensitive data. Developing these security protocols is expected to enable the commercialisation of quantum computing, enhancing their adoption and accessibility.Read moreRead less

This project aims to help companies and government flagships (including Australian) to achieve quantum supremacy- to build a computer based on quantum physics so complex that it outperforms all conventional computers. There is a race to do so because quantum computers will have a huge technological, scientific and economical impact. But currently the error rate of quantum computers is still too high. The devices are immensiley complex, but the models used to drive them are far too simplistic. This project will provide accurate and innovative models in this new era of quantum complexity, thus better controls, which will be tested on cloud-based quantum computers. The expected outcomes are robust quantum computers towards quantum supremacy.Read moreRead less

This project aims to determine whether applications of small quantum devices for communication are commercially feasible with today's or tomorrow's technology. One of the main challenges when engineering future quantum information processors is that complex quantum states are hard to prepare and control and there will be severe limitations on the size of quantum computers for the foreseeable future. Most proposals for applications of quantum information processing require very large quantum computers.
