Quantum information theory underpins and motivates the quantum revolution in computation and communication technology. Led by Professor Howard Wiseman based at Griffith University, the research in QIT is broad-based, including new algorithms/protocols for quantum information processing, quantum estimation and metrology using quantum information technology, feedback-control of quantum information processing devices, and generating novel quantum correlations using optical networks and local processors. The QIT Program collaborates with both theory and experimental programs in the Centre, as well as with partner organisations NASA, NIST, and the National University of Singapore.
