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.

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 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 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

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

Quantum information and communication is a new paradigm in information technology which utilises quantum physics to improve current limitations in speed, security and fidelity of information transmission and processing, extending the present Electronics and Photonics devices. Future applications will include teleportation, cryptography and ultimately quantum computation. We propose to investigate these applications using continuous (CW) laser beams and the Einstein-Podolsky-Rosen (EPR) quantum entanglement, which is generated via a pair of optical parametric oscillators. The advantages of CW over the established single photon technology is better detection efficiency, wider data bandwidth and compatibility with existing Photonics technology.Read moreRead less
