| Research Abstract |
In this research, we deal with quantum spin feedback control systems under continuous measurements and derive theoretical limitation on convergence rate of quantum states to target states in quantum filters and quantum feedback systems. We also derive observation systems and feedback systems to attain multi-qbit entangled states on quantum spin systems.
