Manufacturing, controlling, manipulating and measuring continuous-variable quantum entanglement. Quantum entanglement is a feature of the quantum world which results in objects, which once interacted, remain interlinked even when separated by vast distances. We are approaching the stage where this so-called "spooky action at a distance" will be technologically useful. This project aims to place Australia at the front of quantum entanglement research.

Summary
Quantum state translation in integrated optics: enabling multicolour quantum processing. This project aims to use nonlinear effects in photonic waveguide devices to shift the energies of photons, single particles of light, from one state to another. This will have a profound impact on provably secure quantum communication and potentially provide novel routes to the building of a quantum computer.

Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminish ....Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminishes performance. Here, we propose a new and unique nanostructure positioning technique incorporated directly into the growth process. It interfaces bottom-up technologies with device fabrication, facilitating incorporation of nanostructures in photonic devices, and may be transferrable to a variety of other systems.Read moreRead less

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

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. Via optical quantum information experiment ....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. 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
