The Centre for Quantum Computer Technology is an Australian multi-university collaboration undertaking research on the fundamental physics and technology of building, at the atomic level, a solid state quantum computer in silicon together with other high potential implementations. The objective is underpinned by a vigorous semiconductor research program that includes a sophisticated quantum measurement capability at ultra-low temperatures.

Established in 2000 through funds from the Australian Research Council and participating institutions, the Centre has nodes at the following institutions; University of New South Wales, University of Queensland, University of Melbourne, UNSW@ADFA, Griffith University, Macquarie University and University of Sydney. The Centre encompasses major research infrastructure at each of the nodes, including an extensive semiconductor nanofabrication facility, crystal growth, ion implantation, surface analysis, laser physics, high magnetic fields/low temperatures, and has substantial theoretical support.
