Decoherence and the Nature of System-Environment Correlations
A. Pernice ; W. T. Strunz ;
Date 1 Sep 2011
AbstractWe investigate system-environment correlations based on the exact dynamics of a qubit and its environment in the framework of pure decoherence (phase damping). We focus on the relation of decoherence and the build-up of system-reservoir entanglement. In the commonly employed regime where the qubit dynamics can be described by a Markov master equation of Lindblad type, we find that decoherence is complete while the total state is still separable - no entanglement is involved. In general, both "separable" and "entangling" decoherence occurs, depending on temperature and initial qubit state. Moreover, we find situations where classical and quantum correlations periodically alternate as a function of time in the regime of low temperatures.
