Quantum Teleportation...

...over the actual internet.

Two teams have independently (one in China and one in Canada) sent quantum entangled information over commercial fiber optic networks. This is an important step to being able to use quantum teleportation to transmit real information.

Quantum teleportation does not allow the passage of information faster than light because decoding the entanglement requires a key, which must be sent independently by conventional means. It does, however, allow for the transmission of information by extremely secure methods, as you need both the information and the key to get the message. It may also be possible to do it wirelessly using laser communication techniques - and that, my friends, is how spaceships will send truly secure messages...
