Cool.

"A quantum communication has been sent across a record 144 kilometres (90 miles) using a process which may one day be used to send secret messages across space via a network of satellites.

Quantum teleportation involves "entangling" two particles so that any change to the state of one also occurs instantly in its twin, wherever it may be.

The researchers entangle a pair of photons and then fire a single photon at one of the pair. The resulting interaction changes the state of both entangled photons, effectively teleporting a quantum bit of information - known as a qubit - from one place to another.

The entangled photons behave "like psychic twins", the researchers say: even if they are far apart, a disturbance to one affects the other - an oddity that Albert Einstein dubbed "spooky interaction.""

I was just researching this yesterday and I thought the record was 600 km.

Maybe It's two different things, your 600 km record is the one for quantum cryptography using photons in a fiber cable, and >>1's is for doing quantum communication without a specific carrier. (Just guessing here)

Quantum communication without a specific carrier is not possible. Even entanglement doesn't mean information can be carried faster than light. See http://en.wikipedia.org/wiki/No_communication_theorem
