Simulating quantum states of matter: connecting theory to applications in science and technology. Quantum phenomena are ubiquitous and critical to the functioning of many modern technological devices, for example sensors and computer chips used in mobile phones.

Quantum phenomena are ubiquitous and critical to the functioning of many modern technological devices, for example sensors and computer chips used in mobile phones. Although great strides have been made in recent decades in describing quantum phenomena theoretically, computational modelling is an essential ingredient to describe real experiments and devices. This project aims to develop the next generation of computational tools aimed at two major themes: characterising topological states of matter, and modelling non-equilibrium phenomena. These tools will be invaluable for the design and modelling of quantum devices and novel materials and will enable the development of the next generation of technological devices.Read moreRead less
Novel aspects and applications of quantum measurement theory. The first aim is to develop further a novel formalism for quantum measurement theory based on retrodiction (rather than prediction). The second is to apply this theory to non-Markovian systems (in which the measurement is smeared-out in time). The third is to combine quantum measurement theory with natural selection better to understand the appearance of the everyday world. The expected outcomes include a deeper understanding of quant ....Novel aspects and applications of quantum measurement theory. The first aim is to develop further a novel formalism for quantum measurement theory based on retrodiction (rather than prediction). The second is to apply this theory to non-Markovian systems (in which the measurement is smeared-out in time). The third is to combine quantum measurement theory with natural selection better to understand the appearance of the everyday world. The expected outcomes include a deeper understanding of quantum physics and the establishment of new techniques for analysing problems in quantum communication and quantum-limited technologies. These advances are significant both fundamentally and, at the dawn of the quantum information age, in practice.Read moreRead less

This project aims to provide new knowledge about the relationships between energy, entropy and information in the quantum realm of nanoscale machines and few-atoms systems. The Second Quantum Revolution is currently underway, and represents the merging of thermodynamic concepts of heat and work, with quantum concepts of information processing and entanglement.

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
Turbulent cascades in superfluid Flatland. This project aims to answer open questions in turbulence by stirring many tiny whirlpools (vortices) into a superfluid Bose-Einstein condensate. It seeks to determine how vortex dynamics redistribute energy across broad length scales in superfluids, how turbulence arises from instabilities, and how turbulence redistributes energy in multicomponent superfluids.
