This is a pretty good analogy for explaining why "communication" is the wrong term. It does get wrong the hidden variable thing, which others are pointing out.

This is a pretty good analogy for explaining why "communication" is the wrong term. It does get wrong the hidden variable thing, which others are pointing out. A better analogy would be like I create a pair of coins one of which only turns up heads and the other only turns up tails, but you can't tell which is which until you flip them, and I put them in a bag and they each draw one, travel apart, flip, and deduce. But this is still wrong because the coins had their true state "inside" them the whole time. The part about quantum probability comes in where the coins don't decide which one of them is which until they are flipped (but they decide together, consistently).
