Mark Saffman is the Johannes Rydberg Professor of Physics at the University of Wisconsin–Madison and director of the Wisconsin Quantum Institute (WQI). He is known for his work on neutral-atom quantum computing using Rydberg interaction and he is also the Chief Scientist for Quantum Information at Infleqtion (formerly ColdQuanta)[1]. In 2008, he was elected a Fellow of the American Physical Society for his contributions to atomic and optical physics[2] , and in 2014 he was named a Fellow of Optica for his contributions to neutral-atom quantum computing with Rydberg-state interactions[3] . In 2025, he was co-awarded the 9th John Stewart Bell Prize for pioneering contributions to quantum simulation and quantum computing with neutral atoms[4]. He is also the recipient of the 2026 Norman F. Ramsey Prize, awarded for outstanding contributions to atomic, molecular, and optical physics[5] .
Education and career
[edit | edit source]Saffman earned a BSc in applied physics from the California Institute of Technology in 1981 and a PhD in physics from the University of Colorado Boulder in 1994.[6] After positions in industry and at Risø National Laboratory in Denmark, he joined the UW–Madison faculty in 1999, where he became associate professor in 2004 and full professor in 2007.[6] He has served as director of the Wisconsin Quantum Institute and has held editorial roles with Physical Review journals.[6]
Saffman has concurrently held an industry role as Chief Scientist for Quantum Information at ColdQuanta/Infleqtion since 2018.[6][7]
Research
[edit | edit source]Saffman’s research is in atomic physics, quantum optics, and quantum information processing with neutral atoms, especially using the Rydberg blockade mechanism to implement entangling quantum gates.[1] His review article “Quantum information with Rydberg atoms” (with T. G. Walker and K. Mølmer) in Reviews of Modern Physics helped consolidate the field.[8] His group reported deterministic entanglement of two neutral atoms via Rydberg blockade and a neutral-atom CNOT gate in 2010.[9]
