About me

I am currently a senior researcher and a tech lead at the Institute for Quantum Computing, Baidu. Previously, I was a postdoctoral fellow in Norbert Lütkenhaus’s optical quantum communication theory group, at the Institute for Quantum Computing (IQC), University of Waterloo. Before that, I was a postdoctoral research associate in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge, where I worked with Hamza Fawzi. I received my PhD degree in quantum information from the University of Technology Sydney (UTS:QSI) in 2018, under the supervision of Prof. Runyao Duan and Prof. Mingsheng Ying.

My research focuses on quantum information science, an interdisciplinary field at the intersection of quantum physics, mathematics, and computer science. My expertise lies in understanding the capabilities and limitations of quantum resources, as well as their usage in quantum computation and quantum communication.

I am deeply interested in the mathematical foundations and optimization techniques of quantum information theory. I am also dedicated to the field of quantum software engineering, with a focus on bridging the gap between scientific advancements and functional products that can benefit both industry and society.

I was a recipient of the Beijing High-level Talents Funding Program (top 30).
