Professor Jonathan Barrett
Professor of Quantum Information Science, Department of Computer Science
About
Professor Jonathan Barrett is a member of the Quantum Group at the Department of Computer Science in Oxford, and a Visiting Fellow at the Perimeter Institute for Theoretical Physics, Canada.
His research is interdisciplinary, spanning computer science, physics and the philosophy of physics. His main interests are in quantum information science and the foundations of quantum theory. His work focuses on developing new ways in which quantum systems can be used for tasks such as computation and cryptography, and on the use of tools from information science to address the conceptual problems of quantum theory.
