Graeme Smith (physicist)

Graeme Smith is a Canadian physicist specializing in quantum information theory and quantum computing. He is an associate professor in the Department of Applied Mathematics at the University of Waterloo and a faculty member at the Institute for Quantum Computing (IQC) at Waterloo. Smith was previously a researcher at IBM's Thomas J. Watson Research Center and later a professor at the University of Colorado Boulder, where he was a Fellow of JILA and served as director of the Center for Theory of Quantum Matter. He is known for contributions to quantum communication theory, including the discovery of superactivation of quantum channel capacity (where two quantum channels each with zero capacity can together have a positive capacity). In 2023, he was elected a Fellow of the American Physical Society for his contributions to quantum information physics.
