Irfan Siddiqi

Siddiqi was born in Rawalpindi, Pakistan, and is a direct descendant of the well-known leader of the Khilafat Movement, Muslim activist, journalist and poet, Maulana Mohammad Ali Jauhar (Urdu: مَولانا مُحمّد علی جَوہر). Siddiqi moved to New York City at an early age. He attended the Bronx High School of Science, in the 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 went on to Harvard University to complete his undergraduate education, earning an A.B. with distinguished honors (cum laude) in Chemistry and Physics in 1997.{{cite web|url=https://physics.berkeley.edu/people/faculty/irfan-siddiqi|url-status=dead|title=Irfan Siddiqi profile|website=University of California (Berkeley) website|archive-date=25 April 2024|access-date=19 May 2024 |archive-url=https://web.archive.org/web/20240425032141/https://physics.berkeley.edu/people/faculty/irfan-siddiqi}}

Inspired by superconductivity and superconducting digital circuits during a summer internship at HYPRES, Inc., he enrolled at Yale University for his doctoral studies. His graduate work focused mainly on aluminum hot-electron bolometers for microwave astronomy. Upon receiving his Ph.D. in 2002, he remained as a postdoctoral fellow at Yale, under Michel Devoret and Rob Schoelkopf, to research high frequency measurement techniques for superconducting qubits.{{Cite web |title=AP Alumni Spotlight: Irfan Siddiqi receives the 2021 Joseph F.

His post-doctoral work resulted in the development of the 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 faculty member in the summer of 2005, and is currently a full professor in the Physics Department. In 2015, his laboratory was awarded the UC Berkeley Award for Excellence in Laboratory Safety, awarded by the Berkeley Office of Environment, Health and Safety.{{cite web |url=http://news.berkeley.edu/2015/12/03/physics-lab-wins-grand-prize-for-safety/ |title=Physics lab wins grand prize for safety |website=University of California Berkeley website|date=3 December 2015|archive-url=https://web.archive.org/web/20240519213550/https://news.berkeley.edu/2015/12/03/physics-lab-wins-grand-prize-for-safety/|archive-date=19 May 2024|url-status=dead|access-date=19 May 2024}}

Siddiqi's research is mainly focused on the fields of quantum electrodynamics and cQED. His current research interests include quantum error correction, multi-partite entanglement generation, quantum simulation of high-correlated condensed matter and high-energy physics theories, and single photon detection.

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.{{cite web|url=http://today.lbl.gov/2016/03/30/irfan-siddiqi-of-materials-sciences-wins-cal-teaching-award/|title=Irfan Siddiqi of Materials Sciences Wins Cal Teaching Award|website=Berkeley Lab, University of California website|archive-date=31 December 2016|url-status=dead|archive-url=https://web.archive.org/web/20161231074919/https://today.lbl.gov/2016/03/30/irfan-siddiqi-of-materials-sciences-wins-cal-teaching-award/|access-date=19 May 2024}} In 2021, Siddiqi was awarded the Joseph F. Keithley Award For Advances in Measurement Science "for fundamental advances in superconducting parametric amplifiers, including the development of the Josephson traveling wave parametric amplifier, and for their application to quantum measurement and control."{{cite web|url=https://www.aps.org/programs/honors/prizes/prizerecipient.cfm?last_nm=Siddiqi&first_nm=Irfan&year=2021|title=Prize Recipient|publisher=American Physical Society}}

As the director of the Advanced Quantum Testbed, Siddiqi and his team are on a mission to develop a digital quantum computer based on superconducting circuits to tackle fundamental science applications relevant to the US Department of Energy. The project aims to collaboratively advance the field by incorporating state-of-the-art quantum hardware into an open-access research tool for the science community.

Siddiqi resides with his family, including two children, in California.
