Abstract

We study entanglement dynamics in the presence of correlated environmental noises. Specifically, we investigate the quantum entanglement DYNAMics of two spins in the presence of correlated classical white noises, deriving Markov master equation and obtaining explicit solutions for several interesting classes of initial states including Bell states and X form density matrices. We show how entanglement can be enhanced or reduced by the correlation between the two participating noises.
