Towards the theory of control in observable quantum systems

摘要: An operational description of the controlled Markov dynamics quantum-mechanical system is introduced. The feedback control strategies with regard to dynamical reduction quantum states in course real-time measurements are discribed terms filtering these states. concept sufficient coordinates for a posteriori from given class introduced, and it proved that they form classical process values either state operators or vector space. general problem optimal discussed corresponding Bellman equation space derived. results illustrated example semigroup instantaneously observed at discrete times evolves between measurement according Schroedinger equation.
