Quantum Teleportation

...which doesn't mean anyone's going to be beamed up any time soon. Nor is it an ansible - the information still remains stubbornly below the speed of light.

But scientists have now managed to "teleport" information through 100km of fiber optic cable. What's important about this?

Teleported information can't be intercepted - it's the ultimate encryption for high security data, and one day it may be one of the principles of the internet. Oh, and of course, teleportation in free space can cover longer distances, allowing communication between, for example, ships on the sea. Or in space.

(Makes signals intelligence rather more interesting, doesn't it).
