Research interests:
Zhong group theoretically investigates hybrid quantum system and its potential applications to, e.g., quantum transduction, quantum metrology, with a great emphasis on the practical protocols to coherently connecting different quantum platforms. The research topics play important roles in quantum networking and distributed quantum architectures. The group welcomes students with great interests in generic quantum information theory or quantum Shannon theory.
