Jue XU

I am a PhD student in CS at the University of Hong Kong. I earned a master’s degree in CS from the University of Maryland and a master’s degree in physical sciences from the University of Chicago. I was an undergraduate student of Fudan University.

My research interest lies in the fundamental interplay between physics and computer science. Currently, I am working on the complexity of quantum simulation algorithms and related problems. I am also interested in the formalism of quantum computation. Please feel free to email me if you would like to discuss any potential project.
