Description

The path integral form of the propagator for a stochastic Schroedinger equation is used to derive stochastic differential equations on the quantum phase space of interacting q-bits in a random environment. The equations can be considered as an approximate 'classical' model of the quantum system. Predictions of the model are compared with that of the exact quantum equations for various examples of the environment operators
