About Me

Riley Chien is a graduate student in the Whitfield Group. His research interests revolve around algorithms for quantum computers, in particular simulating physics and chemistry.

In 1929, Paul Dirac said, ”The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble.” Since then, we have used approximations and computational techniques to try to overcome our inability to find such closed form solutions to the equations regarding complex physical systems. Recently, quantum computers have emerged as a powerful tool that, in the near future, may help us solve such problems. My research focuses on figuring out how we can use quantum computers to figure out the complex wavefunctions that electrons configure themselves around nuclei.
