  • Abstract A Markovian model for a quantum automata, i.e. an open quantum dynamical system with input and output channels and a feedback is described. A multi-stage version of the theory of quantum measurement and statistical decisions applied to the optimal control problem for quantum dynamical discrete-time objects is developed. Quantum analogies of Stratonovich nonstationary filtering and Bellman quantum dynamical programming for the discrete time are obtained. The Gaussian case of quantum one… CONTINUE READING
