China launches world’s first hack-proof quantum trunk line

 

China has 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

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. 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.
