We review the standard treatment of open quantum systems in relation to quantum entanglement, analyzing, in particular, the behavior of bipartite systems immersed in the same environment. We first focus upon the notion of complete positivity, a physically motivated algebraic constraint on the quantum dynamics, in relation to quantum entanglement, i.e. the existence of statistical correlations which can not be accounted for by classical probability. We then study the entanglement power of heat…

Evolution Equations for Quantum Semi-Markov Dynamics
TLDR
This work analyzes the emergence of a dephasing term when moving from one type of master equation to the other, and concludes that such an approximation always leads to a Markovian evolution for the considered class of dynamics.
