How is that different or better than just transmitting information at light speed over fiber? Excuse the ignorant question.

  It is (in theory) capable of transmitting the entire quantum state. It's the star trek transporter version of teleportation for quantum mechanical systems.

    It's the star trek transporter version of teleportation for quantum mechanical systems. No. No it isn't. It's not teleportation, because transit still occurs at non-instantaneous rates, and it is effectively slower than light speed travel when you include the overhead of the protocol. A near-light-speed rocket ship could literally accomplish the same thing. It is not a gateway technology that opens a portal to a destination. It clones state, and can replicate an infinite series of clones at a station, via transmission of state. At best it could be called a matter replicator, but it is not teleportation.

    Oh, I see - the transmitted information is far "less" than the quantum state itself.

      indeed. To convey the single quantum state |φ> we only need to send 2 bits, provided we pre-allocated our "receiving" particle correctly (which as far as we currently know has to be one of an entangled pair).
