Abstract
Stochastic representation for interaction of quantum systems is formulated which allows to replace some of them by equivalent but purely commutative random sources. The formalism is applied to two-level systems interacting with Gaussian thermal bath. Strong-coupling non-Marcovian effects and besides long-living fluctuations in common susceptibility of two systems subjected to the same bath are considered.
