Generation of Werner states and preservation of entnglement in a noisy environment
arXiv:quant-ph/0504090 · doi:10.1016/j.physleta.2005.08.033
Abstract
We study the influence of noisy environment on the evolution of two-atomic system in the presence of collective damping. Generation of Werner states as asymptotic states of evolution is described. We also show that for some initial states the amount of entanglement is preserved during the evolution.
