China's launch of quantum satellite major step in space race

[...] a true satellite-based network would make it possible to send quickly encrypted messages in an instant around the world and open the door to other possible uses of the technology.

China has in turn been repeatedly accused by the U.S. of hacking into computer systems to steal commercial secrets and information that could harm American national security.

Quantum messaging could become a major defense against hackers and have applications ranging from military and government communications to online shopping.

Pan Jianwei, chief scientist on the satellite project, was quoted by the official Xinhua News Agency as saying the launch proved China was no longer a follower in information technology, but "one of the leaders guiding future IT achievements."
