Quantum science and applications

In addition to the interesting new physics quantum processes and devices are beginning to uncover, these exotic phenomena have important practical applications.

One such area is quantum cryptography the science of sending secret messages via a quantum channel. It uses properties of quantum mechanics to establish a secure key, a process known as quantum key distribution. This key can then be used at a later stage to send encrypted information.

Quantum techniques can also be applied to reducing the noise present in laser beams, a process known as squeezing. We currently have an extensive research program investigating the application of squeezing and other quantum noise reduction techniques in the laser interferometers used to detect gravitational waves.

Classically chaotic systems display an unpredictability associated with small variations in the initial conditions. However, strategies exist to steer chaotic trajectories towards stable fixed points. This project will investigate if similar strategies can be used to control chaos in the quantum regime.

Quantum defects in diamond have been used to realise new frontiers in quantum technology. This project aims to investigate the properties of the known quantum defects in diamond in order to determine how superior defects in diamond and its related materials can be either engineered or rapidly discovered.

Heavy atomic nuclei may fission in lighter fragments, releasing a large amount of energy which is used in reactors. Advanced models of many-body quantum dynamics are developed and used to describe this process.

This project will construct a 3D optical lattice apparatus for ultracold metastable Helium atoms, which will form an experimental quantum-simulator to investigate quantum many-body physics. A range of experiments will be performed such as studying higher order quantum correlations across the superfluid to Mott insulator phase transition.
