Dr. Wenyuan Wang is a Research Assistant Professor at the University of Hong Kong (HKU) Physics department. He received his Bachelor of Science degree from HKU in 2015 and his PhD degree from the University of Toronto in 2020 under the supervision of Prof. Hoi-Kwong Lo. He worked then as a Postdoctoral fellow at the Institute of Quantum Computing, Waterloo in the group of Prof. Norbert Lutkenhaus for a year and rejoined HKU in 2021.

Dr Wang's main research interest is quantum communication, especially the design, security proof, and optimization of quantum key distribution (QKD) protocols. He is interested in QKD systems in practical scenarios, quantum networks, as well as the combination of novel computational techniques (e.g. classical machine learning and semi-definite programming) with QKD, and he also collaborate closely with experimentalists on various QKD projects. Moreover, he is interested in expanding the linear optical platform for QKD to other quantum communication and computing tasks, as well as potentially quantum machine learning.
