This project aims to extend the density and coherence of qubits stored in superconducting-based quantum processors, by exploring the concept of hybrid quantum systems. Quantum computers are expected to impact a diverse range of sectors, from medicine to national security. This project seeks to develop an enabling technology, a memory, for scaling a quantum computer constructed from superconducting circuits, such as those being developed in commercial laboratories. Such scaling would improve the capacity of these processors to tackle complex problems. The quantum technology developed in this project will have immediate application in transforming a widely-used technique for studying the nanoscale structure of biomolecules - distance measurements in electron spin resonance spectroscopy.Read moreRead less

This project aims to develop a new analytical method and integrated platform technology for time dependent, in situ monitoring of chemical reactions. The proposed research will capitalise on recent developments made in the field of diamond-based quantum sensing to enable the resolution of chemical species and their concentrations within the timescales associated with many important reaction systems. This project thus expects to generate knowledge in both quantum metrology and physical chemistry. Moreover, the realisation of this technology has significant potential to improve the design and manufacture of important advanced materials, ranging from clean energy production and storage, to pharmaceutical development and drug discovery.Read moreRead less
Quantum algorithms for quantum chemistry. This project aims to develop more efficient algorithms to simulate quantum chemistry on quantum computers. Quantum computers have the potential to perform calculations that would be intractable for even the largest supercomputers, but need to be programmed in a radically different way to achieve this speed.

This project aims to develop more efficient algorithms to simulate quantum chemistry on quantum computers. Quantum computers have the potential to perform calculations that would be intractable for even the largest supercomputers, but need to be programmed in a radically different way to achieve this speed. One of the most important applications of quantum computers is to simulate quantum mechanics to predict the properties of molecules and materials, and thereby design them. Current quantum algorithms are very resource intensive, making them impractical for the foreseeable future. The expected outcome of this project is to provide much more efficient algorithms that can be run on quantum processors in the near future.Read moreRead less
Unconditional photonic entanglement verification and quantum metrology using fast, ultra-high-efficiency photon detectors. Scientists can currently only give in-principle demonstrations of the powerful advantages offered by the quantum physics of photons – particles of light. A true quantum technology revolution, that genuinely exploits photons’ exotic nature, requires methods and apparatus that work unconditionally. The main barrier is the extreme fragility of quantum properties due to unavoida ....Unconditional photonic entanglement verification and quantum metrology using fast, ultra-high-efficiency photon detectors. Scientists can currently only give in-principle demonstrations of the powerful advantages offered by the quantum physics of photons – particles of light. A true quantum technology revolution, that genuinely exploits photons’ exotic nature, requires methods and apparatus that work unconditionally. The main barrier is the extreme fragility of quantum properties due to unavoidable losses. This project will overcome this barrier by developing innovative loss-tolerant protocols and devices that unconditionally show and exploit quantum effects, both for long-distance applications and ultra-precise measurement technologies. This collaboration will bring the world’s best photon detectors to Australia, as a key resource for this work and for future research.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. 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 ....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. 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

The aim of this project is to establish a complete theory of resources for quantum networks, by determining the relation between these resources, their symmetry properties, and effective ways of calculating capacities. Critical issues, such as the networking of quantum computers, quantum teleportation and secure communication, require a complete theory of resources. The expected outcome of this project is a rigorous foundation for resources in quantum information that may be used to address these issues.Read moreRead less

Quantum physics and complexity. How much information about a system’s present is needed to predict its future? This project aims to show that the answer fundamentally depends on how information is stored. Simulations of partially random processes are critical in real-world applications. Surprisingly, theory suggests that a simulation must store much more classical data (like bits) than is required to determine its output. This wastes precious resources.

This project aims to show that the answer fundamentally depends on how information is stored. Simulations of partially random processes are critical in real-world applications. Surprisingly, theory suggests that a simulation must store much more classical data (like bits) than is required to determine its output. This wastes precious resources. Via optical quantum information experiments, the project aims to demonstrate and characterise how storing and handling data in quantum states massively reduces this complexity overhead. Another goal is to use novel quantum optics ideas to greatly reduce communication complexity in important remote processing tasks.Read moreRead less
