Chengyong Hu received his Ph.D. from Wuerzburg University (Germany) and Institute of Semiconductors (CAS) in 2000. He worked as postdoctoral researcher at Institute of Semiconductors (CAS) in 2000 - 2002. Then he went to Tohoku University(Japan) as JST researcher at RIEC in 2002-2004. After that he moved to University of Bristol (UK) as Research Assistant, Research Associate and Research Fellow from 2004 to 2020. He joined the Beijing Academy of Quantum Information Sciences in 2020.

 

His earlier research focussed on magneto-optical properties in semiconductors, optically detected magnetic resonance technique, spin coherence and dynamics in semiconductors, time-resolved Faraday/Kerr rotation technique, and cavity quantum electrodynamics (CQED). Since 2004, his research interest has turned to semiconductor-based quantum technologies. He predicted two optical gyrotropic phenomena, i.e., giant Faraday rotation and giant circular birefringence induced by a single quantum-dot-confined electronic spin in optical micocavities (2008-2009, PRB), and proposed the concepts of spin-based quantum transistors (2016-2017, PRB), which could work as deterministic quantum gates, photon entangler, spin-photon quantum interface, quantum routers, quantum repeaters, etc (2008-2021, PRB). At BAQIS, he is building the quantum photonics laboratory to implement the proposed quantum transistors and related devices, as well as single quantum dot devices.
