🎯 The GHZ state was conceived in 1989 by Daniel Greenberger, Michael Horne, and Anton Zeilinger. The name comes from the first letters of their surnames.
🎬 The theme of secret elections with quantum protection appears in cyberpunk: in Stephenson's 'Snow Crash,' characters vote using crypto keys, but only quantum mechanics promises absolute secrecy.
