Main interests:

My main research interests are the foundation of quantum mechanics and their potential application in quantum information theory. I try to find out the better understanding and applications of the quantumness.  I have focused on the quantification of entanglement, quantum discord and coherence,  the re-understanding of the quantum uncertainty,  the experimental measurement of these quantumness, and their properties including the monogamy, the evolution under different environment, disentangling and so on. As to the appliciations, I have also  studied how quantum features induce the quantum advantage of quantum information processing task such as the the roles in nondemolition measurement, the quantum speed limit and the quantum speedup in some quantum algorithms etc..

In recent years,  I am interested in the quantum theory of the open quantum systems based on different physical systems such as quantum optical systems, superconducting systems etc. I mainly focus on the dynamical process and its description methods,  the quantum thermodynamics, the connection between quantum entanglement and some particular quantum optical phenomena.
