Trajectory Tracking of Stochastic Open Quantum Systems Based on Online Estimated State Feedback Control

An online estimated state feedback control for trajectory tracking in stochastic open quantum systems is proposed in this paper, which is based on the Lyapunov-based control method. By inducing the error between the controlled state, and the target state as the error state, the trajectory tracking problem of the quantum system is transformed into the error state transition control problem. The quantum state online estimation method QST-OADM is applied to estimate the state of the error state system online, and the tracking control laws are designed by using the quantum Lyapunov stability theorem for driving the stochastic open quantum system from an arbitrary initial state to an arbitrary trajectory. The numerical simulation experiments and results analyses are given. The trajectory tracking control can be transformed to the state transfer control, and the online estimated state feedback can be realized based on the output obtained. This work studies the trajectory tracking control of stochastic open quantum systems based on the online estimated state feedback. The work also conducts sufficient numerical simulation experiments, demonstrating the efficiency of the proposed method. image
