Quantum Noise and Quantum Maps.
Z. Haba

We represent quantum evolution as a random classical evolution described by a stochastic differential equation defining a Markov process. We discuss a discrete version of the dynamics corresponding to a discrete map q(n + 1) = T(q(n)) + r(n), where r(n) are independent random variables. We indicate an extension of the formalism to quantum dynamics on a manifold.
