Crossing quantum-classical boundaries in a single particle. This project is aimed at constructing and observing an individual quantum system that can exhibit chaotic behaviour under controllable conditions. It is a long-sought goal of modern physics that can become reality for the first time in the world, thanks to the unique availability in Australia of the most quantum-coherent single spin ever made and a long history of theoretical advances in the field.

This project is aimed at constructing and observing an individual quantum system that can exhibit chaotic behaviour under controllable conditions. It is a long-sought goal of modern physics that can become reality for the first time in the world, thanks to the unique availability in Australia of the most quantum-coherent single spin ever made and a long history of theoretical advances in the field. Turning a spin into a chaotic system will uncover the true nature of the quantum-classical boundary, and verify whether an underlying classical chaotic dynamics ultimately influences the behaviour of quantum systems. It is expected that the discoveries made will illuminate the path towards the technological exploitation of increasingly complex quantum devices.Read moreRead less

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. 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 processes and develop methods to enhance the performance of today's quantum computers. Noise characterisation and mitigation should have commercial value and benefit research groups working to develop quantum technologies, both in Australia and internationally.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.

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 project aims to investigate the effects of a fundamental minimum length on the nature of gravity and on how accurately we can make measurements in our world. The key challenge is to combine our best theories of fundamental physics to model what happens at ultra-short distances. This project will generate new knowledge at this interface by using a novel approach inspired by information theory. The expected outcomes are new connections between fundamental limitations on measurements, the nature of gravitation, and ultra-small-scale quantum physics. The benefit of this work is breaking the logjam in answering the most important open question in all of physics: how to unite quantum theory and gravitation.Read moreRead less
