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 noisy quantum devices. The expected outcomes of the project are refined methods to optimise quantum measurements in today's rudimentary quantum machines. This will provide a significant benefit to the Australian community, advancing the development of disruptive quantum technologies.Read moreRead less
Complex quantum dynamics for technological applications. This project aims to characterise dynamics of a quantum system immersed in a complex surrounding, such as a quantum computer interacting with an environment that remembers the computer’s past. Since there are no known methods for battling the effects of the environment on the computer when they are intertwined, this project will develop tools to combat these adverse effects. The project will discover physics of complex dynamics and investi ....Complex quantum dynamics for technological applications. This project aims to characterise dynamics of a quantum system immersed in a complex surrounding, such as a quantum computer interacting with an environment that remembers the computer’s past. Since there are no known methods for battling the effects of the environment on the computer when they are intertwined, this project will develop tools to combat these adverse effects.

Outmaneuvering correlated noise in quantum computers. The project aims to characterise and control quantum machines available today. These machines overwhelmingly suffer from noise with complex structures. Thus, a key target of the project is to develop a theory to describe and manipulate complex quantum processes. The project then intends to apply this theory to commercial-grade quantum computers. This approach is anticipated to lead to a new understanding of time-correlated complex quantum pro ....Outmaneuvering correlated noise in quantum computers.

This project aims to experimentally demonstrate a device needed to bus quantum information between defect clusters in large scale quantum computers. Quantum computers could transcend limits of today’s ‘classical’ computers. Diamond is a proven platform for small-scale quantum computing and simple quantum algorithms have already been demonstrated using small clusters of diamond defects. To build a large-scale quantum computer that can realise the potential of quantum computing, a device must be invented to bus quantum information between defect clusters. This project will experimentally demonstrate physical mechanisms that were theoretically identified for the operation of such a device. This is expected to make a quantum bus for large-scale diamond quantum computers possible.Read moreRead less

Mesoscopic quantum reality in the light of new technologies. Evidence for the Schrodinger cat that defies macroscopic reality has emerged for systems of several atoms, ions or photons, resulting in a Nobel award in physics in 2012.

Evidence for the Schrodinger cat that defies macroscopic reality has emerged for systems of several atoms, ions or photons, resulting in a Nobel award in physics in 2012. However, developments in quantum science technology make these states experimentally accessible at an increasingly mesoscopic level. This project will develop a theory to test mesoscopic realism, nonlocality and decoherence in experiment, focusing on cold atom and ion trap systems. This project will study multipartite nonlocality based on Bell's theorem, the Einstein-Podolsky-Rosen paradox and Schrodinger's quantum steering. As well as having fundamental significance, these demonstrations are potentially useful for metrology, secure quantum cryptography and ultra-sensitive detectors.Read moreRead less
