✦ Synopsis

Experiments with trapped atomic gases have opened novel possibilities for studying the evolution of nonequilibrium finite quantum systems, which revived the necessity of reconsidering and developing the theory of such processes. This review analyzes the basic approaches to describing the phenomena of equilibration, thermalization, and decoherence in finite quantum systems. Isolated, nonisolated, and quasi-isolated quantum systems are considered. The relations between equilibration, decoherence, and the existence of time arrow are emphasized. The possibility for the occurrence of rare events, preventing complete equilibration, are mentioned.

We study the density matrix for systems with an arbitrary linear dissipative mechanism at finite temperature. We show how one may derive the tunneling Lagrangians using general methods in statistical mechanics. The derivation is phenomenological in nature and as such does not proceed from any partic

We describe in a unified way universal operations for quantum systems with arbitrary finite dimension and show some links among them. In particular, we discuss a connection between optimal universal cloning and optimal state estimation. We then describe the operation of the depolarising quantum chan
