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
Quantum measurement as a resource. Advanced quantum computers will use modular measurements significantly enhancing their capabilities. However, due to the noisy environment, the measurements may have nontrivial effects on the computation. Making best use of realistic (hence imperfect) measurements is a challenging problem that hinders the development of these technologies. This project, using modern tools of resource theory, aims to design optimal realistic measurement procedures for near-term ....Quantum measurement as a resource.

When quantum is not desirable: quantum noise vs. quantum technologies. One of the key remaining obstacles to the successful deployment of quantum computers & sensors in science, industry, and society is the existence of noise sources that are themselves quantum, and thus have an unmatched potential for disruption. This project will attack this problem by providing (i) a detailed understanding of the impact of quantum noise sources, and developing protocols to (ii) characterize and (iii) overcome ....When quantum is not desirable: quantum noise vs. quantum technologies. One of the key remaining obstacles to the successful deployment of quantum computers & sensors in science, industry, and society is the existence of noise sources that are themselves quantum, and thus have an unmatched potential for disruption. This project will attack this problem by providing (i) a detailed understanding of the impact of quantum noise sources, and developing protocols to (ii) characterize and (iii) overcome the negative effects such realistic noise entails. In taking this necessary step for the implementation of these breakthrough technologies, it will not only significantly advance knowledge but will have a direct impact in the development of a technology in which Australia and other leading nations are heavily invested.Read moreRead less

The project aims to develop a quantum computer processor based on a new technology developed by Professor Dzurak in 2014-15. Remarkably, the qubits, or processing elements, utilise the silicon metal-oxide semiconductor field-effect transistors that constitute today’s microprocessor chips, so existing production plants can be used to fast-track development. The project will realise proof-of-principle systems with 10-20 qubits, to resolve critical issues related to readout, error correction, and long-distance on-chip coupling, to take the technology to a commercial-ready stage. Quantum computing is one of the great scientific challenges of this century, with important applications in pharmaceutical design, finance and national security.Read moreRead less

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 develop computational tools to study exponentially complex many-body systems, and use them to model novel quantum technologies. Physics has a deep and broad impact on our modern lives, via computing, the internet, mobile telephones, GPS, space travel and medical technologies. This project will demonstrate the potential of quantum devices, with significance and impact both inside and outside physics. The project will simulate quantum systems ranging from quantum circuits for early universe simulation to boson sampling devices using Bose-Einstein condensates and plasmonic systems. Through modelling recent advances, and proposing robust, ultra-sensitive interferometers as one application, the project expects to enhance capability and understanding of quantum science.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
