It is said that quantum entanglement cannot transmit information between two points faster than light because the observed states are random. Assuming classical information theory, it's clear that if I measure photon A as 'up', than its entangled partner B must be in state 'down'. A prediction that is certain to occur carries zero (Shannon) information. However, if we consider the analogy of a coin toss: 'up' here, 'down' there, I win; "down" here, "up" there, you win; it seems we are both informed of the outcome at precisely the same instant. If I'm the first to measure the quantum state here, its seems analogous to a coin toss here, the outcome of which you are instantly informed there.
