TITLE: Towards Semiconductor Spin and Topological Quantum Computing

ABSTRACT: Semiconductor spin and topological quantum chips have been considered as one of the most promising platforms for quantum computing. In comparison with several other platforms, the fabrication techniques of semiconductor quantum computing chips have a great advantage in the compatibility to the state-of-the-art technology employed in the semiconductor chip industry of today. In this talk, after a brief introduction to different quantum computing platforms pursued worldwide, I will present our recent effort and advancements in several aspects, towards study and development of semiconductor spin and topological quantum devices and qubits, including materials growth, device design, fabrication, control electronics, and fundamental physics. The challenges and possible future directions in the realization of semiconductor quantum processors will also be presented and discussed.

BIO: 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 Professor in 2003-2014. He has been appointed Chair Professor at Peking University from 2010 and Director of Beijing Key Laboratory of Quantum Devices at Peking University from 2017. From 2021, he has also been appointed Chief Scientist and Executive Director for the Division of Quantum Computing at Beijing Academy of Quantum Information Sciences. He is a Fellow of the American Physical Society and a Fellow International of the Japan Society of Applied Physics. 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.
