In this paper we study Chernoff averages for time evolution operators. We consider the time evolution of quantum oscillator defined by compositions of random affine phase-space transformations and the diffusion limit of such compositions in the sense of Feynman–Chernoff iterations. The Fokker–Planck equation for the evolution of quasi-probability distribution functions is provided and the problem of decoherence of quantum states in interference experiments is numerically investigated.
