    That’s not the part you were trying to say couldn’t be done. ;) You were trying to argue that quantum entanglement couldn’t be used to communicate, clearly it can.

    The FTL bit is the science fiction premise of the thread. ;)

      That is indeed that bit I was saying couldn’t be done. Entanglement alone can’t be used to communicate; a signal has to be sent conventionally over the distance.

      The FTL bit is physically impossible, so it’s not really “achievable in a reasonable time-frame”

        This you?

        I’m familiar with quantum entanglement. It doesn’t work because you have no way of affecting which state you’ll measure, and thus what state the other particle will be in.

        That’s exactly the part they DID get working.

          No, they did not. Someone finding away to choose the state a wave function collapses into would break quantum physics at a fundamental level. It would literally be the biggest upset in science in human history.
