Chinese Physicists Teleport Photons Over 100 Kilometers

Via: MIT Technology Review:
So these guys clearly have their eye on the possibility of satellite-based quantum cryptography which would provide ultra secure communications around the world. That’s in stark contrast to the few kilometres that are possible with commercial quantum cryptography gear.
Of course, data rates are likely to be slow and the rapidly emerging technology of quantum repeaters will extend the reach of ground-based quantum cryptography so that it could reach around the world, in principle at least.
But a perfect, satellite-based security system might be a useful piece of kit to have on the roof of an embassy or distributed among the armed forces.
Something for western security experts to think about.
