Abstract

The dissipative dynamics of two interacting qubits coupled to independent reservoirs at nonzerotemperatures is investigated, paying special attention to the entanglement evolution. The counter-rotatingterms in the qubit-qubit interaction give rise to stationary entanglement, traceable back to the ground statestructure. The robustness of this entanglement against thermal noise is thoroughly analyzed, establishingthat it can be detected at reasonable experimental temperatures. Some effects linked to a possible reservoirasymmetry are brought to light.
