Gravitational waves are expected to offer humanity a completely new spectrum with which to study the Universe. Australia has been a pioneer in the quest to open up this new spectrum. This project will allow Australia to play a key role in a world-wide project which aims for the first time to enable gravitational waves to be detected from black holes and neutron stars throughout the universe. It will give Australia access to developed technologies, and will be a major boost to physical science research and education.Read moreRead less
Interferometry beyond the Standard Quantum Limit. This research aims to realise measurements below the Standard Quantum Limit (SQL) using advanced quantum optic and opto-mechanical techniques. This is of fundamental interest as the SQL is yet to be observed for a macroscopic object. It is also of particular significance to second generation gravitational wave detectors which are expected to be limited by the SQL. This project will develop an opto-mechanical sensor capable of achieving SQL sensit ....Interferometry beyond the Standard Quantum Limit. This research aims to realise measurements below the Standard Quantum Limit (SQL) using advanced quantum optic and opto-mechanical techniques. This is of fundamental interest as the SQL is yet to be observed for a macroscopic object. It is also of particular significance to second generation gravitational wave detectors which are expected to be limited by the SQL. This project will develop an opto-mechanical sensor capable of achieving SQL sensitivity as well as develop and test techniques to surpass the SQL. These techniques will be directly applicable to long base-line gravitational wave detectors.Read moreRead less
Non-Gaussian states and entanglement distillation for Continuous Variable quantum information protocols. Amplifiers are important devices for electronic, computer as well as telecommunication industries. In the quantum world where light's corpuscular nature is prominent, amplification of a beam of light will have its associated noise penalty. This noise penalty sets limit to many quantum optical applications. This proposal aims to use a method based on conditional detection to realize a 'noisel ....Non-Gaussian states and entanglement distillation for Continuous Variable quantum information protocols. Amplifiers are important devices for electronic, computer as well as telecommunication industries. In the quantum world where light's corpuscular nature is prominent, amplification of a beam of light will have its associated noise penalty. This noise penalty sets limit to many quantum optical applications. This proposal aims to use a method based on conditional detection to realize a 'noiseless linear amplifier' that has no noise penalty probabilistically. Realization of this key device is central to extending the range of quantum communication, such as quantum cryptography. It also has applications in quantum computing and the potential to enhance sensitive measurements.Read moreRead less

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.

The Standard Quantum Limit and Beyond. The uncertainty principle sets limits on the sensitivity to which any measurement can be made - the standard quantum limit (SQL). This limit is yet to be reached on a macroscopic object and, until recently, was regarded as unsurpassable. Due to the rapid improvement in optical measurement technology developed for Gravitational Wave Astronomy, there is now the prospect of experimentally reaching the standard quantum limit within this decade. This project wi ....The Standard Quantum Limit and Beyond. The uncertainty principle sets limits on the sensitivity to which any measurement can be made - the standard quantum limit (SQL). This limit is yet to be reached on a macroscopic object and, until recently, was regarded as unsurpassable. Due to the rapid improvement in optical measurement technology developed for Gravitational Wave Astronomy, there is now the prospect of experimentally reaching the standard quantum limit within this decade. This project will harness much of this technology to achieve the SQL. It will also experimentally develop new quantum measurement techniques to surpass this limit.Read moreRead less

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-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
Quantum repeater technologies for continuous variable. It is often said that quantum mechanics will revolutionise 21st century technologies in the same way as Maxwell's electromagnetic theory did in the 20th century.

It is often said that quantum mechanics will revolutionise 21st century technologies in the same way as Maxwell's electromagnetic theory did in the 20th century. Amongst these technologies, quantum information, and more precisely quantum communication techniques are expected to revolutionise telecommunication systems, both in terms of security and capabilities. A near term application of quantum communication, that is already semi-commercial, is Quantum Key Distribution, a novel cryptographic method whose absolute security is ensured by the laws of physics. The range of transmission of these quantum communication protocols, however, is currently limited, a limitation that this proposal aims at alleviating. Read moreRead less
