  • China has demonstrated way to send data over long distances which is potentially unhackable.
  • It relies on “quantum cryptography” and a satellite sending data via photons from space to earth.
  • The implications could be huge for cybersecurity, making businesses safer, but also making it more difficult for governments to hack into communication.

China has demonstrated a world first by sending data over long distances using satellites which is potentially unhackable, laying the basis for next generation encryption based on so-called “quantum cryptography.

Last August, China launched a quantum satellite into space, a move which was called a “notable advance” by the Pentagon.

Using this satellite, Chinese researchers at the Quantum Experiments at Space Scale (QUESS) project, were able to transmit secret messages from space to Earth at a further distance than ever before.

The technology is called quantum key distribution (QKD). Typical…
