Feynman Diagrams and the Quantum Stochastic Calculus

Abstract

We present quantum stochastic calculus in terms of diagrams taking weights in the algebra of observables of some quantum system. In particular, we note the absence of non-time-consecutive Goldstien diagrams. We review recent results in Markovian limits in these terms.
