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.

The polaritonics project combines theoretical and experimental research on exciton-polaritons in semiconductor microcavities. We investigate emergent quantum phenomena far from equilibrium and their applications for next-generation optoelectronics devices. Theoretical work is linked to the ANU experiment on polariton Bose-Einstein condensation, which is the first of its kind in Australia.
