Phys. Rev. A 63, 032106 (2001) [6 pages]Stability of quantum states under dissipationReceived 24 January 2000; revised 25 August 2000; published 14 February 2001 Using a simple stability argument for the entropy production we find the conditions for a state to remain pure under certain dissipative dynamics. We also calculate the time scales for the onset of decoherence when these conditions are not satisfied. © 2001 The American Physical Society URL:
