Quantum Continual Measurements and a Posteriori Collapse on Ccr

  title={Quantum Continual Measurements and a Posteriori Collapse on Ccr},
  author={Viacheslav P. Belavkin},
A quantum theory for the Markovian dynamics of an open system under the unsharp observation which is continuous in time, is developed within the CCR stochastic approach. A stochastic classical equation for the posterior evolution of quantum continuously observed system is derived and the spontaneous collapse (stochastically continuous reduction of the wave packet) is described. The quantum Langevin evolution equation is solved for the general linear case of a quasi–free Hamiltonian in the… CONTINUE READING
