Phys. Rev. A 57, 840–844 (1998)Bounds on decoherence and errorReceived 26 December 1996; published in the issue dated February 1998 When a confined system interacts with its walls (treated quantum mechanically), there is an intertwining of degrees of freedom. We show that this need not lead to entanglement, hence decoherence. However, it will generally lead to error. The wave-function optimization required to avoid decoherence is also examined. © 1998 The American Physical Society URL:
