Quantum Theory Group

Professor Sarah Croke

‌‌I am a theoretical physicist, interested in quantum information, quantum foundations, and related areas. Quantum information is a broad and interdisciplinary field sitting somewhere at the boundary between mathematics, computer science, and theoretical and experimental physics. Working in this field I have enjoyed learning parts of all of these, but remain a physicist, and am most interested in understanding quantum theory and its implications.‌

I have been at the University of Glasgow since September 2013. Before that I spent almost 6 years in Waterloo, Ontario, at the Perimeter Institute, where I was first a postdoctoral fellow and later a PSI fellow.
