This will require a different and more complicated theoretical approach to that which worked for optical lasers, but the result will be a device with a spectral flux which is orders of magnitude better than the current state of the art.Read moreRead less
Storage of non-classical light in a solid. A new scheme for storing and recalling coherent light pulses based on 'slow light' has been demonstrated. The aim of this project is to show how this can best be achieved in a solid to enable practical applications. A range of materials will be investigated. The novel feature of the storage is the maintenace of the coherence information and a noise analysis will be made to determine whether it is experimentally possible to store non-classical light.
Probing the Universe with gravitational waves: from cutting-edge technology to astronomy. The direct detection of Einstein's elusive gravitational waves will not only confirm one of the most important theories in physics, it will unleash a new form of radiation (in addition to electromagnetic) with which to study the Universe. Our participation in this quest continues Australia's role in the vanguard of new astronomy and its exploitation. This proposal will produce scientists highly trained in ....Probing the Universe with gravitational waves: from cutting-edge technology to astronomy.

Our participation in this quest continues Australia's role in the vanguard of new astronomy and its exploitation. This proposal will produce scientists highly trained in areas of national priority, including frontier technologies such as photonics and smart information use through GRID computing. Developing ways to build instruments of almost unimaginable sensitivity fosters innovation leading to spin-offs into other areas of optical sensing - fundamental research resulting in economic benefit.Read moreRead less

Quantum optics has the potential to provide highly accurate physical measurements, and to improve the speed and security of communication. The spatial modes of a light field provide a new and interesting basis for these investigations.
This fellowship proposes to generate spatially correlated quantum light beams, applying them to spatial positioning applications, such as atomic force microscopy, and to quantum communication protocols. I will experimentally develop general techniques to losslessly combine multiple quantum spatial modes, and demonstrate multi-mode quantum correlations in a light beam. I will investigate the potential of this light to cryptography, densecoding, and atomic force microscopy.

Detection and Control of Ultracold Atoms. Australia is at the forefront of research into atom lasers, a device that may be as important to science and technology this century as the laser was in the last. This project will provide important theoretical tools for developing the atom laser from an object of intrinsic interest to a useful tool. It will develop Australian scientific expertise in this area, and provide training for the next generation of Australian scientists.
Quantum Photonics and Imaging. Photonics is an expanding industry and its technology to date is essentially all classical, it uses light as a wave. In Quantum Photonics we want to carry out fundamental research that makes full use of the quantum properties of photons. We want to demonstrate novel and better ways to create, transfer, store and manipulate information both in space and time. This will lead to new applications such as quantum-cryptography, optical teleportation, and quantum-imagin ....Quantum Photonics and Imaging.

In Quantum Photonics we want to carry out fundamental research that makes full use of the quantum properties of photons. We want to demonstrate novel and better ways to create, transfer, store and manipulate information both in space and time. This will lead to new applications such as quantum-cryptography, optical teleportation, and quantum-imaging, initially with a few, later with many pixel. All these are particularly suitable for our proven technology of nonclassical continuous laser beams.Read moreRead less
