Henry Yuen is a Ph.D. student in the Theory of Computation group at MIT. He received his bachelor’s degree in mathematics and minor in computer science from the University of Southern California. His research focus concerns the rich interplay between quantum physics, computational complexity, communication complexity and information theory. Some of Yuen’s work has focused on the topic of quantum randomness expansion, whereby classical users can interact with untrusted quantum devices to force them to produce secure random bits. In one of his results, he showed that one only needs a constant amount of seed randomness to catalyze the production of an unlimited amount of output randomness. Recently, Yuen has been working on hardness amplification of quantum games.
