Physics Department, The University of Michigan, Ann Arbor, Michigan 48109-1040, USA(Dated: August 16, 2011)Analyses of phenomena exhibiting ﬁnite-time decay of quantum entanglement have recently attracted con-siderable attention. Such decay is often referred to as sudden vanishing (or sudden death) of entanglement,which can be followed by its sudden reappearance (or sudden rebirth). We analyze various ﬁnite-time decays(for dissipative systems) and analogous periodic vanishings (for unitary… Expand
