Quantum Optics and Quantum Information
Our current research work focuses on the experimental and theoretical studies of quantum optics, especially applications in Quantum Information Processing. We investigate the interplay of interactions between light and matter, pursue robust long distance quantum communication, scalable quantum computation and quantum simulation.
