In quantum information theory there are the additional resources of entanglement and quantum communication. 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

Summary
Quantum enhancement for ultra-precise atomic sensors. This project will investigate methods for drastically improving the sensitivity of measurement devices derived from atom interferometers. This will enable experimental tests of certain aspects of fundamental physics, as well as practical tools such as ultra-precise geodesy for minerals exploration.
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.

The aim of this theoretical physics project is to develop ultra-precise sensing capabilities for two main applications: ultrastable inertial sensors for improved navigation and gravimetry, and to search for signatures of quantum gravity. This project expects to improve the performance of quantum sensors via the use of machine optimisation, and may lead to much-needed experimental data to help guide one of the most challenging problems in theoretical physics: the quantisation of gravity. The expected outcomes of this project are enhanced quantum sensor design, leading to improved inertial sensing technology. This should provide benefits such as improved capabilities for minerals exploration and monitoring the movement of ground water.Read moreRead less

Optical realisations of continuous-variable quantum information. The project aims to develop a framework for optical realisations of continuous-variable quantum information. Such realisations offer the potential for major technological advances in quantum information processing in the near future, but are currently impeded by the lack of a well-defined theoretical foundation. This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. ....Optical realisations of continuous-variable quantum information.

This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. Feasible experiments to test and exploit continuous-variable quantum information processing will be proposed. The resulting framework will allow the field to progress beyond proof-of-principle demonstrations and to develop new, technology-driven quantum information protocols.Read moreRead less

Summary
Deterministic photonic quantum gates by amplified optical nonlinearities. Quantum devices will reshape future technology in ways similar to the information revolution heralded by modern computing. This proposal will combine theoretic advances in optical sciences with cutting-edge materials to build photonic quantum gates, removing the last major roadblock on the path to photonic quantum computers and simulators.
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
