A quantum entangled communication system wouldn't have any 'transmission' issues (through mediums, etc), correct?

  You can’t transmit information with quantum entanglement.

    Really? But can't you influence 1 side of an entangled pair, then measure the other side, and you can pass information through the correlation? I thought quantum-entangled FTL communication devices were a legitimate thing.

      Nope. You can’t change the outcome, you can only make an observation on one and then and only then know the state of the other. What is being observed is entirely random.

      Information cannot be transceived faster than light. The thought experiments and whatabouts and whatifs are fun to discuss, especially after drinks - but seeing which spin or collapse or whatever isn't information in the actual definition of information. Information involves entropy and all that stuff is bound by the speed limit.
