Xiao-Liang Qi is a Chinese-born theoretical physicist noted for contributions to Condensed matter physics, Quantum information, and the theory of Topological insulators. He is known for work bridging ideas from Quantum field theory, General relativity, and Many-body physics to address emergent phenomena in low-temperature systems. His research connects concepts from the Sachdev–Ye–Kitaev model, Majorana fermion proposals for quantum computing, and classifications of Topological order.

Early life and education

Qi was born and raised in China and completed undergraduate studies at Tsinghua University where he studied Physics under mentors with ties to institutions such as Peking University and Chinese Academy of Sciences. He pursued doctoral studies at Stanford University under Shoucheng Zhang, engaging with groups affiliated with Stanford Institute for Theoretical Physics, SLAC National Accelerator Laboratory, and collaborations involving Microsoft Research researchers. His doctoral work intersected with research lines associated with Berkeley theorists and had connections to seminars at Princeton University and Harvard University.

Qi held postdoctoral and faculty positions including visiting scholar roles at institutions like Princeton University, Institute for Advanced Study, and research collaborations with Microsoft Research and IBM. He joined the faculty of Stanford University where he became a professor in departments linked to Stanford Institute for Theoretical Physics and collaborative centers such as SLAC National Accelerator Laboratory. Qi has participated in programs at Kavli Institute for Theoretical Physics, Perimeter Institute, and delivered invited talks at conferences hosted by American Physical Society, American Mathematical Society, and International Centre for Theoretical Physics.

Qi developed theoretical frameworks connecting Topological insulator physics with surface states protected by symmetries studied by researchers at Bell Labs and Los Alamos National Laboratory. He contributed to models proposing Majorana fermion bound states in proximity structures related to work at Microsoft Research and experiments at Stanford Linear Accelerator Center. Qi has advanced understanding of the Sachdev–Ye–Kitaev model building on foundations from Subir Sachdev and Alexei Kitaev, linking it to notions from AdS/CFT correspondence and ideas originally explored at Institute for Advanced Study and Princeton University. His papers often bridge methods from Quantum field theory groups associated with Harvard University and MIT and computational approaches used at Caltech and UC Berkeley. He has engaged with classifications of Topological order and symmetry-protected phases in dialogue with work from Kitaev, F. Duncan M. Haldane, David J. Thouless, and research programs at ETH Zurich and University of Cambridge.

Qi authored influential papers coauthored with colleagues linked to Shoucheng Zhang, Shinsei Ryu, and S. C. Zhang that appeared in journals frequented by researchers from Physical Review Letters, Nature Physics, and Science. He contributed chapters in volumes associated with proceedings at Kavli Institute for Theoretical Physics and edits collaborating with scholars from Perimeter Institute and Max Planck Institute for the Physics of Complex Systems. His work is cited alongside foundational texts from Philip W. Anderson, Steven Weinberg, Leonard Susskind, and review articles emerging from APS March Meeting sessions.

Qi received recognition including prizes and fellowships conferred by organizations such as the American Physical Society and international awards comparable to the Dirac Medal (ICTP) and the Sakurai Prize. He has been elected a fellow of professional societies connected to Institute of Physics and participated in award committees alongside members from National Academy of Sciences and panels convened by European Physical Society.

At Stanford University Qi teaches graduate courses integrated with programs at Stanford Institute for Theoretical Physics and supervises doctoral students who have gone on to positions at institutions such as Princeton University, Harvard University, MIT, and UC Berkeley. His mentees collaborate with groups at Microsoft Research, IBM Research, and experimental teams at Lawrence Berkeley National Laboratory and Argonne National Laboratory.

Qi participates in public lectures and conference outreach connected to events hosted by American Physical Society, Perimeter Institute Public Lectures, and university lecture series at Stanford University and Tsinghua University. He has contributed to panels alongside leaders from National Science Foundation, engaged with media associated with Nature, Science, and given interviews for institutional news outlets at Stanford and international forums including International Centre for Theoretical Physics.
