Biographical details

Professor Stephen Bartlett is pursuing fundamental research in the theory of quantum physics. His particular focus is on quantum information theory, including the theory of quantum computing, as well as the foundational issues of quantum mechanics.

Professor Bartlett completed his Ph.D. in mathematical physics at the University of Toronto in 2000. Moving to Australia, he directed his research to the theory of quantum computing, first as a Macquarie University Research Fellow and then as an ARC Postdoctoral Research Fellow at the University of Queensland. Since 2005, he has lead a research program in theoretical quantum physics at University of Sydney, with interests spanning quantum computing, quantum measurement and control, quantum many-body systems, and the foundations of quantum theory.
