Solid-state quantum communication technology. This project will develop the quantum information devices required to create a quantum communication network for the ultra-secure transmission of data. The key technological challenge is to entangle the quantum state of two crystals separated by kilometres, and maintain this entanglement for many seconds.
Observing Einstein-Podolsky-Rosen entanglement with ultracold atomic gases. As a fundamental test of quantum mechanics, the project will demonstrate for the first time the famous Einstein-Podolsky-Rosen paradox in the regime of a macroscopic number of entangled massive particles. As well as enabling the design of new gravitational sensors, the outcomes will give insights into the unification of quantum theory with gravity.
Quantum Phase Transitions In- and Out-of-Equilibrium in Optical Lattices. This project aims to contribute to understanding the physics of quantum many-body systems. A complete understanding of phase transitions in strongly interacting quantum many-body systems is a key step towards solving several open problems in modern physics (eg high temperature superconductors). However, they are extremely difficult to study theoretically or in traditional experiments, due to the underlying strong quantum c ....Quantum Phase Transitions In- and Out-of-Equilibrium in Optical Lattices. This project aims to contribute to understanding the physics of quantum many-body systems. A complete understanding of phase transitions in strongly interacting quantum many-body systems is a key step towards solving several open problems in modern physics (eg high temperature superconductors). However, they are extremely difficult to study theoretically or in traditional experiments, due to the underlying strong quantum correlations. This project plans to take an alternative approach using ultra-cold helium atoms in an optical lattice to form an analogue quantum simulator. This would provide access to a new experimental observable: many-body correlation functions, which should yield new insights. Understanding such systems more deeply may lead to the development of new quantum technologies based on this science.Read moreRead less
Quantum nonlocality tests with ultracold atoms. As a fundamental test of quantum mechanics, we will measure for the first time "spooky action-at-a-distance" for macroscopically large groups of atoms. As well as establishing limits to the size of new quantum devices such as gravitational sensors, we will provide insights into the unification of quantum theory with gravity.
Nonequilibrium states of polariton superfluids. This project aims to design novel nonequilibrium states of a polariton superfluid and to identify why some are more robust than others. Polaritons are hybrid particles of light and matter that exist in thin layers of a semiconductor. At high densities they form a superfluid, exhibiting quantised whirlpools and frictionless flow. The project aims to realise these states in the laboratory and to address one of the challenges of physics: predicting an ....Nonequilibrium states of polariton superfluids. This project aims to design novel nonequilibrium states of a polariton superfluid and to identify why some are more robust than others. Polaritons are hybrid particles of light and matter that exist in thin layers of a semiconductor. At high densities they form a superfluid, exhibiting quantised whirlpools and frictionless flow. The project aims to realise these states in the laboratory and to address one of the challenges of physics: predicting and controlling the emergent properties of materials far from equilibrium. The anticipated outcome is the generation of fundamental knowledge that could be used to guide the design of polaritonic devices such as novel optoelectronic devices for emitting and controlling light.Read moreRead less

Quantum Simulation with Ultracold Metastable Helium in an Optical Lattice. Understanding the behaviour of electrons in a lattice has led to the development of numerous devices now taken for granted in everyday life. But there are still many open questions concerning strongly interacting electrons in a lattice, for example, an explanation of high temperature superconductivity.

Understanding the behaviour of electrons in a lattice has led to the development of numerous devices now taken for granted in everyday life. But there are still many open questions concerning strongly interacting electrons in a lattice, for example, an explanation of high temperature superconductivity. This is because modelling these systems is hard, due to the quantum correlations between particles, while impurities in solid state materials hinder experimental studies. This project aims to develop a quantum simulator using ultracold helium atoms in an optical lattice to model such systems. Correlation functions will be measured by detecting individual atoms, providing a new observable to characterise many-body lattice states.Read moreRead less

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

This project aims to advance diamond quantum technologies by discovering and engineering defects, innovating quantum microscopy techniques and enabling large-scale diamond quantum computing. Quantum technologies could transcend the limits of today’s current technologies. Defects in diamond are a proven platform for the development of quantum microscopes which could yield images of nature at the atomic scale and quantum computers that may solve problems too difficult for classical computers. This project will employ an integrated research approach, spanning fundamental theory to device design and demonstration. Key anticipated outcomes are international collaboration and knowledge, capability and training in quantum microscopy and computing. This will benefit Australia by securing its global competiveness in the emerging market of quantum technology.Read moreRead less
