China on Friday launched the world’s first 2,000-km-long ‘hack proof’ quantum communication line between Beijing and its commercial capital Shanghai that cannot be wiretapped. Quantum communications have ultra-high security. It is impossible to wiretap, intercept or crack the information transmitted through them, state-run Xinhua news agency reported.

The line is the world’s first trunk line of secure quantum telecommunications. The Jing-Hu (Beijing-Shanghai) Trunk Line connects Beijing, Jinan, Hefei and Shanghai. Officials said that the quantum satellite was expected to provide a fool-proof hack-free communication which makes foreign powers to monitor or intercept China’s communication systems.

The line is connected with the world’s first quantum satellite, which was launched by China in August last year, through a station in Beijing. The satellite is nicknamed ‘Micius’ after a Chinese philosopher and scientist who conducted optical experiments.

Bai Chunli, president of the Chinese Academy of Sciences (CAS), talked with staff in Hefei, Jinan, Shanghai and Xinjiang Uygur Autonomous Region, through the line. He also had a video call with Austrian quantum physicist Anton Zeilinger through the satellite.
