A Quantum Ping

nphoton.2014.215-f1We’re still light years away from Star Trek-style transporters, but according to a September 2014 article in Nature Photonics (a peer-reviewed subsidiary of Nature) physicists at the University of Geneva have succeeded in teleporting data–in this case, the quantum state of a photon–over a distance of some 25 kilometers. The breakthrough occurred this March in the lab of Professor Nicolas Gisin and bests the previous record by a factor of four. The team responsible likens the experiment to the action of pool balls, in which a collision between two balls destroys them both but still sends its “information” or effect to a third. Because the “teleportation” occurred over fiber optic wires, the backbone of the internet, it brings the age of Quantum Computing that much closer.
