Chinese Scientists Break Quantum Teleportation Record

One more step down the long road to beaming yourself to work.

In the latest experiment, researchers entangled two photons and zapped the higher-energy one through a special 10-mile-long free-space tunnel, instead of a fiber one. The distant photon was still able to respond to the changes in state of the photon left behind, an unprecedented achievement.

It worked because the team “maximally entangled” the photons, using spatial and polarization modes, according to Ars Technica. About 89 percent of the information was maintained, also an improvement over previous experiments.

The work was done at the Hefei National Laboratory for Physical Sciences at Microscale and the Department of Modern Physics, University of Science and Technology of China, Hefei.

Researchers warned that this brings us not closer communicating information without a traditional signal transmission and that technically no matter was really moved. We say, forget that noise. Sell your car! Cancel your plane tickets! Teleportation has arrived!
