    The idea is this:

    2 particles are quantum entangled. Whatever happens to one instantly happens to the other regardless of distance.

    So you establish a state that means “0” and a state that means “1” and you can send binary.

    At a minimum, you have quantum Morse code.

      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 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”
