Theory of quantum information and quantum communication

Principal investigator

Our group's research focuses on in-depth study and exploration of quantum information theory, quantum communication, quantum computing, quantum nonlocality, and their potential applications for practical quantum information processing, by closely relating feasible experimental implementations. In terms of quantum communication technology, the emphasis is on how to achieve for longer distance communication, higher communication speed, better stability and reliability in real-life situation, and with guarantee of communication security. We are dedicated to the research of new communication schemes and related key technologies under the goal of pushing forward the practical and network-based development of quantum communication. In the course of theoretical aspects, we are also undertaking research on characterizations of quantum correlations, non-locality test of quantum mechanics and associated applications, construction of new Bell inequalities, classic and quantum many-body problem, and low-dimensional condensed matter physics.
