The UNSW Canberra laboratories have an international reputation for fast, quantum-noise-limited, linear photodetectors with associated electronics and they also make use of multiple infrared single-photon-detector modules, as well as microwave digital and analogue test and measurement equipment.
The CQC²T research laboratories at UNSW Canberra are located within the School of Engineering and Information Technology. The detection capabilities of the laboratories have expanded to include a superconducting nanowire single-photon counter. The inception of CQC²T hailed significant redevelopment in all laser laboratories, with new temperature control systems, air-current control systems and pollutant-minimisation protocols being instituted.
The laboratories house an infrared Nd:YAG laser with feedback control of intensity noise (500 / mW CW at 1064 nm), a frequency- doubled Nd:YAG laser with feedback control of intensity noise (1W CW at 532 mm), an infrared fibre laser with feedback control of intensity noise (5W CW at 1550 nm) and a near-infrared Titanium-Sapphire laser with frequency and intensity noise control (2W CW at 860 nm). Each laboratory houses a home-built optical parametric amplifier that is used as a source of non-classical light in several subsequent experiments.
