Mixing Time of Open Quantum Systems via Hypocoercivity

Watch a 47-minute lecture from Duke University researcher Di Fang at the Simons Institute exploring novel approaches to estimating mixing time in open quantum systems. Learn about a theoretical framework that separates the analysis of Hamiltonian and dissipative components, avoiding the traditional challenge of spectral gap estimation for Lindbladian generators. Discover how concepts from classical kinetic theory's hypocoercivity can be applied to construct energy functionals for quantum systems. Gain insights into this fundamental problem in physics and quantum information science that has important implications for understanding quantum system behavior and dynamics.
