State Steering of Electron Spin System by Multi-Step Quantum Measurement

摘要：

　　A control scheme of electron spin system by multi-step quantum measurement is proposed.In each control step, unitary evolution and quantum measurement are performed by turns until the system is in the target state.If we regard each control step as a random jump in a Markovian stochastic process, the whole control scheme could be modeled using a Markovian chain.Simulation results show that this control scheme can achieve the control target in finite step just as what is suggested by theoretical calculation.
