It doesn't imply no correlation. It implies 50% correlation. If particle 1 outcome was up, the probability that particle 2 outcome is down is 1/2. Thus the probability that particle 1 is up and particle 2 is down is 1/2 * 1/2 = 1/4. Accounting the case for when particle 1 is down, the total...

If there are no hidden variables and if there are no communications between the particles, how can the random outcomes of the two measurement devices be perfectly correlated? Like I said, I agree that there could be some correlation (1/2 * 1/2 + 1/2 * 1/2 = 50% anti-correlation). However...

Consider a pair of entangled particles described by a local theory without hidden variables. Because there are no hidden variables, the results of an experiment on one particle of the entangled pair must be perfectly random. Due to locality, the particles also have no way of coordinating the...
