STAFF LISTING

TIMOTHY C. RALPH
BSc (Hons), Macquarie University, Sydney
PhD Australian National University, Canberra

Professor of Physics University of Queensland
Centre Node Manager Queensland
Program Manager Linear Optics Quantum Computation - Theory
Australian Professorial Fellow

 

Tim has extensive experience in theoretical and experimental quantum optics as well as optical implementations of quantum information techniques. Tim had postdoctoral experience at the University of Auckland before being awarded an Australian Postdoctoral Fellowship at the ANU. He moved to the University of
Queensland in July 1999 and took up a QEII Research Fellowship there the following year. Tim has recently been awarded an Australian Professorial Fellowship. Tim managed the Linear Optics Quantum Computation Program established in late 2000, until 2003 when it
was enlarged and split into two programs, theory and experiment, within the new COE. Tim now takes responsibility for the theory component. The program seeks to demonstrate the feasibility and scalability of quantum computational gates based on linear optics and electro-optic feedforward techniques.
