Self-averaging of random quantum dynamics

Stochastic dynamics of a quantum system driven by statistically independent random sudden quenches is studied. We show that with growing frequency of random quenches the system smoothly approaches deterministic limit indicating self-averaging of its temporal evolution. Moreover we reveal that there is an effective (constant) Hamiltonian generating time evolution of self-averaged system directly related to statistical properties of the stochastic driving.
