The previous record was set in 2003.

GENEVA, Switzerland, Sept. 21 (UPI) -- Professor Nicolas Gisin and his team have successfully teleported a photon over 15 miles in its quantum state. The Swiss team of scientists aimed to transport the photon into a crystal without the two touching, and they did just that. The same team were able to accomplish this in 2003, but they were only able to teleport the light a little less than four miles. The reporting of the accomplishment can be found in the latest issue of Nature Photonics.

In May of 2012, a team of scientists was able to teleport a photon between two Canary islands, at a distance of roughly 88 miles. In both situations optical fiber was used to carry the light particle. "The next step is satellite-based quantum teleportation, which should enable quantum communication on a global scale. We have now taken a major step in this direction and will use our know-how in an international cooperation, which involves our colleagues at the Chinese Academy of Sciences. The goal is to launch a 'quantum satellite mission'," physicist Anton Zeilinger said at the time.
