China to lay out massive quantum network for information security
With the maturity of China's quantum information science and technology, an advanced network that is considered unhackable and will provide the most secure encryption technology is ready to commercialise in China, according to Pan Jianwei, a quantum scientist and professor at the University of Science and Technology of China, Xinhua reported on Tuesday.
A quantum communication network between Beijing and Shanghai — the two political and financial centres of the country — is now under construction, and is projected to be put into service by 2016. The 2,000-kilometre network between Beijing and Shanghai is slated to become the world's longest quantum communication network.
China also plans to achieve Asia-Europe intercontinental quantum key distribution by 2020, and is ready to build a global quantum communication network by the 2030, Pan said at the conference. The technology of transmitting quantum states is generating interest due to work in quantum cryptography, which is believed to be able to create "unbreakable" messages, as any attempt to access the encryption will be detected by the system immediately.
