Abstract

Dissipative quantum dynamics is newly formulated in order to study small systems such as quantum stochastic resonators which show stochastic resonance even in a single spin system coupled with stochastic enviroment obeying Arrhenius-type relaxation. This formulation is similar to Zubarev's formulation in non-equilibrium infinite systems. However, the present formulation has the great merit that it is applicable to small finite dissipative quantum systems which are related to quantum information and other mesoscopic devices.
