Markovian quantum subsystems and stabilization design

  • Quantum subsystems have been widely applied in the field of quantum information processing and control, so active control over quantum subsystems is of great importance. For Markovian open quantum dynamical model, some main theoretical results on invariant and attractive subsystems are summarized, and some important properties and their essential meanings are analyzed. Based on these, open-loop Hamiltonian design methods which make a subsystem become invariant and attractive were studied. In particular, the Hamiltonian design of invariance of a subsystem and attractiveness of an invariant subsystem achieved globally asymptotical stabilization of this subsystem. Finally, simulation experiments on a two-level open quantum system were conducted, and results show the validity of the proposed method.
