Stochastic pure state representation for open quantum systems
arXiv:1609.09636 · doi:10.1016/0375-9601(86)90692-4
Abstract
We show that the usual master equation formalism of Markovian open quantum systems is completely equivalent to a certain state vector formalism. The state vector of the system satisfies a given frictional Schrödinger equation except for random instant transitions of discrete nature. Hasse's frictional Hamiltonian is recovered for the damped harmonic oscillator.
