But the quantum hype train must be fueled! AFAIK the only value of quantum communications seems to be that it can provide a tap-proof channel to send one bit of information per entangled photon to a receiver, but only if they have already established the entanglement and have established the timing of the "quantum message" transmission. This new discovery suggests that the two entangled parties can both encode those qubits with a message and both receive the other party's message before losing the entanglement? What am i missing here?
