Professor Stephen Bartlett is a theoretical quantum physicist and Professor in the School of Physics and Director of the University of Sydney Nano Institute. He leads a team pursuing both fundamental and applied research in quantum information theory, including the theory of quantum computing. He is a Chief Investigator in the Australian Research Council Centre of Excellence in Engineered Quantum Systems (EQUS), where he leads a research program on Designer Quantum Materials. He is the inaugural Lead Editor of the APS journal PRX Quantum. He sits on the Executive Board of the Sydney Quantum Academy, on the Quantum Expert Advisory Board of the new quantum computing initiative at Transport for NSW, and on the International Scientific Advisory Board of the Stewart Blusson Quantum Matter Initiative at UBC. He previously served as the Associate Dean Research for the Faculty of Science (2020-2023). He is a Fellow of the American Physical Society (APS), the Australian Institute of Physics (AIP), and the Royal Society of NSW.

Stephen 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 led a research program in theoretical quantum physics at the University of Sydney, with interests spanning quantum computing, quantum measurement and control, quantum many-body systems, and the foundations of quantum theory.
