Abstract
For n-qubit stochastic open quantum systems, an online quantum state estimation (OQSE) algorithm and the associated online estimated-based-state feedback control (OQSE-FC) are proposed in this paper. The proposed OQSE algorithm integrates the online alternating direction multiplier method (OADM) to the continuous weak measurement (CWM). The quantum state feedback control laws are designed based on the Lyapunov stability theorem, and the states for feedback control are online estimated by OQSE algorithm. The convergence of OQSE algorithm and the asymptotic stability of the state feedback control laws are proved.
