Scientists quantum teleport information 90 miles across islands

Quantum teleportation is reaching greater distances, and hopes are high that satellites will be able to use the technology.

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 teleportationwas 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.
