The research interests of the quantum optics group are experimental quantum information, the physics and applications of of atomlight interaction, quantum metrology and nonlinear optics. We are located in the Department of Quantum Science, which is a part of the Research School of Physics and Engineering.
Our group forms a part of the Centre for Quantum Computation and Communications Technology. This ARC Centre of Excellence is based and the University of New South Wales and has nodes at the University of Queensland, University of Melbourne, Griffith Univeristy, UNSW@ADFA as well as the ANU.
