Short Biography

Hongqi Xu is Chair Professor at Peking University and Chief Scientist at Beijing Academy of Quantum Information Sciences. He received his Ph.D. degree in condensed matter physics in 1991 from Lund University, Sweden. From 1991 to 1993, he was employed as Postdoctoral Fellow at Linkoping University, Sweden. In 1993, he returned to Lund University, where he was employed as Research Associate in 1993-1995 and was appointed Assistant Professor in 1995-2001, Associate Professor in 2001-2003, and Full the Professor in 2003-2014. He has been appointed Chair Professor at Peking University from 2010 and served the Director of Beijing Key Laboratory of Quantum Devices at Peking University in 2017-2025. From 2021, he has been appointed Chief Scientist at Beijing Academy of Quantum Information Sciences, where he also served the Executive Director of Division of Quantum Computing in 2021-2025.


He was elected to Fellow of the American Physical Society and to Fellow International of the Japan Society of Applied Physics. He has published more than 300 papers in prestigious scientific journals, including Science, Nature Nanotechnology, Nature Communications, Science Advances, Advanced Materials, Physical Review Letters, and Nano Letters. His current research areas include experimental and theoretical studies of electron transport in quantum structures, topological states of matter, strong correlated systems, semiconductor spin physics and spin qubits, as well as semiconductor-superconductor hybrids for topological quantum devices and quantum computing.
