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. Turning a spin into a chaotic system w ....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. 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
Discrete integrable systems. Discrete integrable systems are a fundamental generalisation of traditional integrable systems. This project, combining 5 world experts from 3 countries and 2 early career researchers, will expand and systematise this new interdisciplinary field, and will place Australia at the forefront of this intensive international activity.
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. This project, using modern tools of resource theory, aims to design optimal realistic measurement procedures for near-term ....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 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
Crises of Leadership in the Eastern Roman Empire (250-1000 CE). Armed conflict, the upheaval of social systems, and environmental crises cause citizens to question their leaders during periods of social change. They also increase religious extremism, including speculations about the imminent end of the world. The period 250-1000 CE reveals many examples of how such crises served leaders who knew how to profit from instability to expand their powers, and how they damaged the reputations of those ....Crises of Leadership in the Eastern Roman Empire (250-1000 CE). Armed conflict, the upheaval of social systems, and environmental crises cause citizens to question their leaders during periods of social change. They also increase religious extremism, including speculations about the imminent end of the world. The period 250-1000 CE reveals many examples of how such crises served leaders who knew how to profit from instability to expand their powers, and how they damaged the reputations of those who did not. Understanding how past leaders of the Roman world addressed these crises in practical and rhetorical ways may provide helpful and timely models of what works (and what does not) for contemporary community and political leaders, even in democratic political societies such as Australia.Read moreRead less
Rethinking the history of Soviet Stalinism. This project will provide a more sophisticated understanding of the complexities of Stalin's Russia by considering critically the data now available in Soviet archives. It will explain how the system evolved in response to real social, economic and international problems, rather than exclusively in response to individual or psychological factors.
New quantitative methods in X-ray imaging using crystal optics. This project will enhance Australian science's international leadership in the area of x-ray imaging. This powerful type of X-ray imaging, which makes use of optical elements made of perfect crystals, is specially tailored to image samples which are invisible to conventional x-ray techniques. Such "extended x-ray vision" is extremely important for imaging in medicine, biology and materials science. Furthermore, we will train x-ray s ....New quantitative methods in X-ray imaging using crystal optics.

New Physics and the quark/lepton family replication puzzle. This project aims to investigate how new physics impacts on the puzzling threefold replication of the elementary particles known as quarks and leptons; these particles provide the foundations for the structure of atoms.

This project aims to investigate how new physics impacts on the puzzling threefold replication of the elementary particles known as quarks and leptons; these particles provide the foundations for the structure of atoms. This theory project seeks to do so in the context of a concentrated worldwide experimental program whose objective is to produce hugely more information about the mysterious replication. Expected outcomes include the construction of new theories that deepen our understanding of elementary particles and their interactions. This should provide significant benefits to intellectual culture and the training of early-career researchers as flexible problem solvers able to innovate in any context in industry or government service.Read moreRead less
