I have a question, after having read about a non-destructive spin measurement experiment, which was cited as one of the top science stories of 2006: http://physicsweb.org/articles/news/10/12/15/1#11 http://optics.org/cws/Articles/View...268?articleId=26434&channel=technology&page=1 So that announcement immediately makes me wonder about Bell's Inequality: http://en.wikipedia.org/wiki/Bell's_inequality#Description_of_Bell.27s_theorem They say that you can't use the "spooky action at a distance" (correlation violation) to communicate information, since you can't predict/measure in advance what an entangled particle's state will be. But the non-destructive measurement experiment shows that you can indeed measure the particle in advance, without significantly disturbing/altering that particle's state (or its entanglement?) Wouldn't this Kerr rotation measurement method then allow for the pre-screening of entangled pairs, based on measurement in advance of state properties like spin? Couldn't this then be used to exploit the correlation violation (aka "spooky action at a distance") in such a way as to permit its use for communication? For instance, using the Alice & Bob example, wouldn't it be possible to use pre-measured entangled electron pairs of known spin state, and use the orientation of the apparatus on one end as a way to modulate an information signal, which would then be detected with the other party through the correlation violation? To me, it would seem intuitive that the answer is yes. Why shouldn't this be able to work? Please, someone kindly take the time to give me a reasoned reply, even if my post sounds ignorant.
