Implementation of classical driving on the quantum level — •Heiko Schröder and Günter Mahler — Universität Stuttgart, 1. Institut für Theoretische Physik, Pfaffenwaldring 57, 70550 Stuttgart

The development of Quantum Thermodynamics [1] in the recent years has shown that thermodynamical concepts can be observed in and produced by quite small quantum systems. The existence of and relaxation to a thermal equilibrium has been found to be dependent on the existence of a suitable, but not necessarily big quantum environment. On this background, we have dealt with the question of the implementation of classical control in quantum systems by quantum systems as another important concept of thermodynamics. Here, we present a sufficient condition for a quantum environment in order to operate as a classical driver of another quantum system.
