In the following sentence: "The einselected states lack coherence, and therefore do not exhibit the quantum behaviours of entanglement and superposition" Wouldn't "interference" be more adequate to describe in a simple manner quantum behavior rather than "entanglement and superposition"? At least I think that it might fit better the quantum behavior that we might see in this particular case if decoherence had not taken place. Normally we would just make many measurements of the system in question prepared every time in the same way and then look at the statistics (distribution) of the results. While entanglement would imply a correlation between two systems (particles in the case of EPR), here we just need to look at one system. A simple example might be a double-slit experiment with some massive particle, where some interaction with the environment might destroy coherence before the particle reaches the screen. In that case we would no longer see an interference pattern. Of course we could apply the concept of einselection to a pair of entangled particles, but the article does mention that.

I understand that "entanglement" in the mentioned paragraph could refer to that between the system and the environment, but if that were the case, perhaps this paragraph could be re-worded to make it more specific. Being this paragraph a kind of introduction, my previous suggestion might still work better as it would not lengthen it. Alexepascual (talk) 18:57, 16 July 2012 (UTC)
