If only we were quantum states, we’d be playing Kirk and Scotty, popping around the universe until the inevitable failure in the transporter circuits.

European and Canadian scientists are pushing the envelope on quantum teleportation after having succeeded in beaming quantum states across some 90 miles in the Canary Islands.

The laser-locked telescopes on the islands of La Palma and Tenerife served as transporter rooms, teleporting information about the state of a pair of “entangled” particles.

The entanglement links the particles such that a change in one is registered in the other despite great distances between them.

Quantum teleportation was first demonstrated in 1997, but distances are growing longer. A Chinese team of researchers also reported teleporting quantum states across a significant distance, 60 miles, in the journal Nature this month.
