Evolution from entanglement to decoherence

Abstracts:
We examine a class of bipartite mixed states which we
call X states and report several analytic results related to the
occurrence of early-stage decoherence or so-called entanglement sudden
death (ESD) under time evolution in the presence of common types of
environmental noise. Avoidance of sudden death by application of purely
local operations is shown to be feasible in some cases.
Key words:
Entanglement, Decoherence, Mixed States
