Abstract: In view of the rapid development of quantum information science, the interest in developing systematic theories for controlling quantum systems is rapidly increasing. In particular, the concept of quantum feedback control has central importance in engineering of reliable quantum technologies, similar to the classical case.

In this talk, we will review some basic notations of quantum mechanics and introduce the dynamics of open quantum systems under the continuous-time measurements. We will then present our results on feedback exponential stabilization of Spin-1/2 systems.

Bio: Weichao Liang received the B.Sc degree in Telecommunication from XiDian University, China, in 2014 and the M.Sc. degree in Automatic from CentraleSupélec-Université Paris Sud, France, in 2016. He is currently working toward the Ph.D. degree in Laboratoire des Signaux et Systemes, CentraleSupélec-Université Paris Sud-Université Paris Saclay under the supervision of Paolo Mason and Nina Amini. His research interests include stabilization of open quantum systems, stochastic control and non-linear control.
