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

This project aims to explore effects of strong interactions on phases of light and matter in complex quantum systems, by mimicking them with surrogates called quantum simulators. The project expects to open up new research directions by building a novel versatile simulator platform from nanoscale superconducting electronic circuits in which all elements are flexibly engineered and precisely controlled. Expected outcomes from the project will include better understanding of complex materials and a certifiable scaling-up pathway towards simulation complexity, future hi-tech manufacturing; and enhanced research capacity in the new interdisciplinary field of quantum engineering. This should help to position Australia as a centre for hi-tech quantum industry leading to both social and 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

Summary
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
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.

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. A heat engine of this kind would provide significant benefits to Australia with its potential to revolutionise how we store and use energy. The project will enable Griffith University to continue its pioneering role in developing this technology and to maintain long-term international collaborations.Read moreRead less

With special-purpose quantum devices on the horizon, the need for novel quantum protocols is of urgent technological and economic significance. Using interdisciplinary methodologies, this project will explore the hypothesis that quantum advantage is associated to a fundamental need for fine-tuning in classical simulations of quintessentially quantum phenomena.
