Primary Investigator

Michael Hatridge is an Assistant Professor of Physics at the University of Pittsburgh. He received his B.S. from Texas A&M University and Ph.D. from U.C. Berkeley under the supervision of John Clarke. He was a postdoctoral associate at Yale University, working with Michel Devoret on topics including quantum measurement, parametric amplification, and bath engineering. His current work focuses on the use of parametric drives to generate quantum controls, including single- and multi-qubit gates and engineered baths, and quantum circuits, including quantum-limited parametric amplifiers and modular quantum computers. He is a recipient of the Michelson Postdoctoral Prize Lectureship, the NSF CAREER Award, the Sloan Research Fellowship, and the 2021 U. Pittsburgh Chancellor's Distinguished Research Award.
