Irfan Siddiqi is an American physicist and currently a Professor of Physics at the Quantum Nanoscience Laboratory (established by him) and the Department of Physics at the University of California Berkeley.[2] He is known for groundbreaking contributions to the fields of circuit quantum electrodynamics and for the development of the Josephson quantum electron pump. In recognition of his pioneering work in superconducting circuits, among other honors and awards, he was awarded with the American Physical Society George E. Valley, Jr. Prize in 2006, "for the development of the Josephson bifurcation amplifier for ultrasensitive measurements at the quantum limit."

Biography

Siddiqi was born in Karachi, the former capital and largest city of Pakistan, but his family moved to New York City while he was young. He did his schooling at the Bronx High School of Science, Bronx, NY, where he developed a strong interest in physics, chemistry and mathematics. His aptitude in physics and mathematics led him to the Columbia University Science Honors Program. He moved on to Harvard University to complete his undergraduate education, earning an A. B. with distinguished honors (cum laude) in Physics and Chemistry in 1997. Inspired by superconductivity and superconducting circuits during his summer internship at HYPRES, Inc., he enrolled at Yale University for doctoral studies, where his graduate work focused mainly on aluminum hot-electron bolometers. Upon receiving his Ph.D. in 2002, he was awarded a postdoctoral research fellowship at Yale for work on superconducting qubits. His post-doctoral work resulted with the development of the Josephson quantum electron pump or a Josephson Bifurcation Amplifier, which makes use of the non-dissipative, non-linear nature of the Josephson junction to realize high gain and minimal back action measurements of quantum systems. He joined the University of California Berkeley as a physics faculty member in the summer of 2006 and is currently a full professor at the Berkeley Physics department. In 2015, his laboratory was awarded the first-ever UC Berkeley Award for Excellence in Laboratory Safety, awarded by the Berkeley Office of Environment, Health and Safety.[3]

Siddiqi's research is mainly focused on the fields of quantum electrodynamics and cQED. His work in collaboration with Robert J. Schoelkopf and Steven Girvin made significant contributions to the development of quantum computing and in developing a new paradigm of circuit QED using superconducting electrical circuits.

His current research interests include coherence measurements of single molecule magnets using novel dispersive magnetometers, topological quantum computation, nanotube based quantum bits, and techniques to make measurements of quantum back action.[4]

Siddiqi was one of the five faculty recipients of the "2016 Berkeley Distinguished Teaching Award", which is the University of California, Berkeley's most prestigious honor for teaching.[5]
