Let's have a set of two actions { goLeftOpenDoor, goRightRiseFlag }, and a deterministic algorithm to pick one action given a completely random input.<p>Alice and Bob are both aware of this algorithm, but they are very far from each other.<p>Alice and Bob each receives one particle from an entangled pair (A,B).<p>Alice makes a measurement on her particle, and so does Bob.<p>They now both also share a meaningless random value.<p>But, since they previously agreed on a way to _do something_ based on a random input, Bob actually picks _goRight_ and he goes right, and raises the flag.<p>Could then Alice know that the flag has been raised ? If so, why isn't it considered as an actual information ?<p>Note : I think I'm really wrong somewhere here (and probably have "divided by zero" several times)... just correct me if/where it's the case.
