Scientists have used quantum teleportation to send information over long distances, with a higher fidelity than ever before.

Quantum entanglement is a strange phenomenon that sounds like science fiction to our classical-physics-focused minds. Basically, two or more particles can become so entwined that changing the state of one instantly changes that of its partners – no matter how far apart they are.

This mechanism – which Einstein himself dubbed "spooky" – can be tapped into to create quantum networks. Pairs of photons can be entangled and separated, allowing data to be "teleported" between them over long distances. As a bonus, these networks could be more secure, since any hackers would garble the data just by trying to read it.

Now, researchers at Fermilab, AT&T, Caltech, Harvard, NASA JPL and the University of Calgary have demonstrated sustained, very accurate quantum teleportation over long distances. The team sent infor
