Quantum Optics & Information Laboratory
The Quantum Optics and Information Laboratory, home to the Optical Quantum Information Program, expanded by 50% in laboratory area, to 120m2, with the advent of CQC2T.
In both old and new laboratory areas, QOIL experiments are performed in spaces that are temperature-controlled, vibration-damped, and optimised for low-light quantum optics experiments. The laboratory is equipped with three (one high-power) femtosecond lasers and two 60 mW violet diode lasers, resting on high-performance vibration-isolated optical tables. Other important equipment includes a number of single photon detectors, multiple nonlinear crystals for generating single photon pairs, custom designed optics, and computercontrolled motion stages for setting the position of optical elements with very high precision. Together these represent a highly reconfigurable test bed for optical quantum information protocols; development of advanced sources of quantum light—such as a high-coincidence-efficiency source of entangled photon pairs; novel detection and feedback schemes; and the study of the fundamental properties of the quantum world. The program enjoys the support of mechanical and electronic workshop facilities.
The Resources for Quantum Information Program operates on the Nathan Campus out of a number of academic offices and postgraduate rooms. Late-model computers are used for numerical simulations. The group members share ideas with each other and visiting scientists at formal and informal seminars and workshops held in various University venues.
