George Siopsis, Professor of Physics, received a B.Sc. degree in Mathematical Physics from the University of Sussex, England, in 1982. He did his graduate work at the California Institute of Technology, where he received an M.S. (1983) and a Ph.D. (1987) in Physics. After spending four years at Texas A&M University as a Research Associate, he joined the Department of Physics and Astronomy at the University of Tennessee in 1991. His CV is available here.
Dr. Siopsis is a theoretical particle physicist currently working on quantum computing and quantum information processing. Together with collaborators at ORNL, he has built a quantum optics laboratory for quantum cryptography, and in particular, measurement-device-independent quantum key distribution in free space, as well as quantum position verification. He has established a fruitful collaboration with ARL and its partners, such as JQI at the University of Maryland, studying topological quantum walks and quantum games with an eye toward elucidating the structure of topological materials and quantum network applications. He has been developing quantum algorithms (quantum machine learning, quantum field theory, quantum walks, quantum games, etc.) and implementing them on existing quantum hardware (IBM, IonQ, D-wave). He succeeded in getting the University of Tennessee and ARL sign a CRADA that establishes commitment to a long-term collaboration between the two Institutions in quantum information processing with a focus on quantum networks. In August 2019, he was awarded a NSF conceptualization grant to explore the creation of a Quantum Leap Challenge Institute at UTK. His research is funded by NSF, DoE/ORNL, ONR, DHS/CIRI, ARO, and DARPA. For more information on Dr. Siopsis's research, please visit the web site of his group.
