According to Associated Press, the work is the closest scientists have come to a real-world quantum encryption system that uses light particles called photons to lock and unlock information instead of random-number "keys." Quantum cryptography depends on a defining discovery in physics: that subatomic
particles can exist in multiple states at once until something interacts with them.
