In this paper, we propose feedback designs for manipulating a quantum state to a target state by performing
sequential measurements. In light of Belavkin’s quantum feedback control theory, for a given set of (projective or
nonprojective) measurements and a given time horizon, we show that finding the measurement selection policy
that maximizes the probability of successful state manipulation is an optimal control problem for a controlled
Markovian process. The optimal policy is Markovian...[Show more]
