Angus Lowe

I am a PhD student at the Center for Theoretical Physics at MIT. My primary interests lie in quantum information science, particularly quantum algorithms, learning properties of quantum states, and complexity. Before MIT, I completed a BSc in computer science and physics at the University of Edinburgh and an MMATH at the University of Waterloo. I also previously worked as a quantum algorithms researcher at Xanadu.
