• If all goes to schedule, China would be the first country to put a quantum communications satellite in orbit, said Wang Jianyu, deputy director of the China Academy of Science's (CAS) Shanghai branch. By 2030, the Chinese network would be extended worldwide, the South China Morning Post reported. It would make the country the first major power to publish a detailed schedule to put the technology into extensive, large-scale use.
  • The satellite would be used to transmit encoded data through a method called quantum key distribution (QKD), which relies on cryptographic keys transmitted via light pulse signals. QKD is said to be nearly impossible to hack, since any attempted eavesdropping would change the quantum states and thus could be quickly detected by dataflow monitors.
  • Governments in Europe, Japan and Canada are about to launch their own quantum communication satellite projects and a private company in the US has been seeking funding from the federal government with a proposal for a 10,000km network linking major cities.
