The dream of hack-proof communication just got a little closer to reality. On August 16, 2016, China launched the world’s first “quantum satellite,” a project the Chinese government hopes will enable it to build a communication system incapable of being hacked. Such a system, if perfected, would allow for encrypted communications between any two devices with absolute certainty that the encryption could not be broken, and with a built-in mechanism for alerting the sender/receiver if someone tried.
