Siddharth Muthukrishnan

Siddharth finished a B.Tech in Engineering Physics from the Indian Institute of Technology, Guwahati. He worked on entropy inequalities at the Tata Institute of Fundamental Research before joining the physics PhD program at USC.

He is now working on quantum annealing, specifically, trying to understand how tunneling and diabatic transitions contribute to the computational power of quantum annealing. He also works on developing mathematical techniques to study both quantum and classical annealing.
