    "abstract": "We examine a class of bipartite mixed states which we call X states and\nreport several analytic results related to the occurrence of so-called\nentanglement sudden death (ESD) under time evolution in the presence of common\ntypes of environmental noise. Avoidance of sudden death by application of\npurely local operations is shown to be feasible in some cases.",
