China Successfully Sends Quantum-Encrypted Message from Space

JIAN-WEI PAN / wired.com

China has sent an "unbreakable" code from a satellite to the Earth, marking the first time space-to-ground quantum key distribution technology has been realized, state media said on Thursday.

The Chinese launched the world's first quantum satellite last August, to help establish "hack proof" communications, according to a report by Reuters.

The satellite sent quantum keys to ground stations in China between 645 km (400 miles) and 1,200 km (745 miles) away at a transmission rate up to 20 orders of magnitude more efficient than an optical fiber, Xinhua News cited Pan Jianwei, lead scientist on the experiment, as saying. Any attempt to eavesdrop on the quantum channel would introduce detectable disturbances to the system, Pan said.
