Wuhan launches world-leading quantum network

Wuhan, Hubei province, launched the world's most advanced civilian quantum communication network on Tuesday, and will soon connect all the city's government bodies, financial institutions and other entities to allow the secure transmission of classified information, according to project managers.

A launch ceremony was held during a laser technology forum in Wuhan hosted by China Aerospace Science and Industry Corp, the major builder of the network. The company mainly develops and produces missiles and carrier rockets but also invests heavily in laser technologies and instruments, which are key components of a quantum communication network.

CASIC said in a news release that the network's operation will ensure the "absolute safety" of the transmission of classified information and will boost the efficiency of such communications.
