Predicting decoherence in discrete models
arXiv:1010.3253 · doi:10.1007/s10773-011-0726-x
Abstract
The general aim of this paper is to supply a method to decide whether a discrete system decoheres or not, and under what conditions decoherence occurs, with no need of appealing to computer simulations to obtain the time evolution of the reduced state. In particular, a lemma is presented as the core of the method.
