I think this article deeply confuses the concept of quantum-entanglement cryptography with teleportation.
If they're transmitting photons, which it's clearly stated that they are, then it's not
teleportation, now is it? They're transmitting entangled photons, not teleporting them, and the reason you'd want to do that is because it defeats a "man in the middle" attack against the communications channel - the act of receiving the photons disrupts the entanglement, and it's impossible to re-entangle them again, so you'd know if you were receiving the transmission direct from your partner, or if a third-party had intercepted and re-transmitted.
This doesn't allow for any sort of FTL communication because there's no teleportation of anything. This is just a kind of special transmission of photons with cryptographic implications. They're not overcoming the speed of light.
