Chinese satellite sends unbreakable code from space

China is hitting the accelerator on space exploration with Chinese scientists becoming the first to send an “unbreakable” code from a satellite to the Earth.

This marks the first time space-to-ground quantum key distribution technology has been realised, in what state agency Xinhua called “laying the foundation for building a hack-proof global quantum communication network”.

The achievement was was published in the authoritative academic journal Nature on Thursday calling it a “milestone”.

China launched the world’s first quantum satellite, Nicknamed “Micius”,  on 16 August last year, to help establish “hack proof” communications.

Xinhua quoted Pan Jianwei, lead scientist of the project QUESS and an academician of the Chinese Academy of Sciences (CAS), saying the satellite sent quantum keys to ground stations in Xinglong, in north China’s Hebei Province, and Nanshan near Urumqi, capital of northwest China’s Xinjiang Uygur Autonomous Region.

When the satellite flies over China, it provides an experiment window of about 10 minutes. During that time, 300 kbit secure keys can be generated and sent by the satellite, according to Pan.

“That, for instance, can meet the demand of making an absolute safe phone call or transmitting a large amount of bank data,” Pan said.
