The Australian Centre of Excellence for Quantum Computation and Communication Technology is an international research effort to develop the science and technology of a global quantum information network, encompassing ultra-fast quantum computation, absolutely secure quantum communication and distributed quantum information processing.

The Centre was established in 2011 with extensive funds from the Australian Research Council, the US National Security Agency, the Semiconductor Research Corporation, the Department of Defence, the New South Wales State Government and the participating Australian institutions: University of New South Wales, Australian National University, University of Melbourne, Griffith University, University of Queensland, UNSW@ADFA and University of Sydney.

The Centre encompasses major research infrastructure, including extensive cryogenic facilites for low noise, high frequency spin control, semiconductor nanofabrication facilities, scanning probe microscope and crystal growth facilities, single ion implantation, extensive laser infrastructure and substantial theoretical support.
