Degradation of Entanglement in Markovian Noise
arXiv:1806.07468 · doi:10.1103/PhysRevA.99.032307
Abstract
The entanglement survival time is defined as the maximum time a system which is evolving under the action of local Markovian, homogenous in time noise, is capable to preserve the entanglement it had at the beginning of the temporal evolution. In this paper we study how this quantity is affected by the interplay between the coherent preserving and dissipative contributions of the corresponding dynamical generator. We report the presence of a counterintuitive, non-monotonic behaviour in such functional, capable of inducing sudden death of entanglement in models which, in the absence of unitary driving are capable to sustain entanglement for arbitrarily long times.
