Beschreibung

Dissipative reservoirs are inevitably present in real experiments and, at low temperatures, typically induce decoherence or even destroy fragile quantum states. However, in the last years it has turned out that they are not always the "bad boys." In fact, they can be exploited as assets to promote cooperative quantum phenomena, for example, in superconducting solid state devices or for cold atomic gases.

In this talk I will first discuss experimental developments and theoretical challenges, and then focus on specific phenomena. These include cooling and entropy reduction in Cooper pair boxes, the almost local generation of Einstein-Podolsky-Rosen entanglement, and photon-charge interaction in circuits with Josephson junctions and resonators.
