If you're willing to read through it, there's a Wikipedia article on Bell's theorem: http://en.wikipedia.org/wiki/Bell%27s_theorem http://en.wikipedia.org/wiki/Bell%27s_theorem The summary: If you assume simple locality (your k and ~k,) you get different results than what quantum entanglement predicts. If you want to get rid of the spooky action at a distance, then you need much, much more complicated hidden variables.
