It's interesting, but it's not a breakthrough, nor does it herald any sort of advance in anything resembling Star Trek transporters, though to its credit I think this is the first Mass Market Science Journalism (TM) article on quantum teleportation I've seen that managed to avoid that faulty comparison, so points for that I guess.

If your transmission is based on quantum entangled photon states, it is physically impossible to eavesdrop without giving yourself away, since the act of eavesdropping 'collapses the quantum superposition' (like when you open the box with Schrodingers cat). They've actually already rolled out systems based on this technology in various places in the world, but there is a lot of work to improve bandwidth and so forth.
I won't say too much more as I'm well outside the field and will probably garble it.
If they manage to implement this shit, we'll be able to have FPS games hosted anywhere in the world!
