A posterior quantum dynamics for a continuous diffusion observation of a coherent channel
Anita Dabrowska, Przemysław Staszewski
We present the Belavkin filtering equation for the intense balanced heterodyne detection in a unitary model of an indirect observation. The measuring apparatus modelled by a Bose f…
Filtering equation for a measurement of a coherent channel
A. Dabrowska, P. Staszewski
A stochastic model for a continuous photon counting and heterodyne measurement of a coherent source is proposed. A nonlinear filtering equation for the posterior state of a single-…
Quantum Stochastic Differential Equation
V. P. Belavkin, P. Staszewski
A semi-classical non-Hamiltonian model of a spontaneous collapse of unstable quantum system is given. The time evolution of the system becomes non-Hamiltonian at random instants of…
Nondemolition observation of a free quantum particle
V. P. Belavkin, P. Staszewski
A stochastic model of a continuous nondemolition observation of a free quantum Brownian motion is presented. The nonlinear stochastic wave equation describing the posterior dynamic…
A Quantum Particle Undergoing Continuous Observation
V. P. Belavkin, P. Staszewski
A stochastic model for the continuous nondemolition ohservation of the position of a quantum particle in a potential field and a boson reservoir is given. lt is shown that any Gaus…
