Abstract
Quantum open systems are described in the Markovian limit by master eq uations in Lindblad form. I argue that common ''quantum jump'' techniq ues, which solve the master equation by unraveling its evolution into stochastic trajectories in Hilbert space, correspond closely to a part icular set of decoherent histories. This is illustrated by a simple mo del of a photon counting experiment.
