I would recommend that anyone who is interested in this and related topics to study the work of W.H. Zurek. His work on quantum information theory over the past few decades is absolutely superlative. http://arxiv.org/find/quant-ph/1/au:+Zurek_W/0/1/0/all/0/1 http://arxiv.org/find/quant-ph/1/au:+Zurek_W/0/1/0/all/0/1
