Photon tests blaze trail for communication

China achieves a quantum jump

China has become the first country in the world to establish photon entanglement at a distance of more than 1,200 kilometers, paving the way for ultrasecure, long-distance quantum communication.

In July, Beijing and Vienna will try to conduct the world's first cross-continental video call using Micius, the world's first quantum communication satellite launched by China last year. It will take more than a decade for such technologies to reach the public, scientists said.

By beaming photons-individual particles of light-between Micius and two receiving ground stations-the Delingha station in Qinghai province and the Lijiang station in Yunnan province, Chinese scientists have shown that these photons could remain entangled despite the stations being more than 1,200 kilometers apart.

This distance is 10 times greater than similar tests done on the ground, which are usually conducted using fiber optics or in open air and are susceptible to interference, according to findings published on Friday in Science, an international journal.
