The three main types include a system based on non-commuting observables, another on non-commuting state vectors, and a system based on Bell's Theorem.
The three main types include a system based on non-commuting observables, another on non-commuting state vectors, and a system based on Bell's Theorem. It involves transmissions of photons between sender and receiver and a measurement of their polarizations by the receiver. It solves the the so- called key distribution problem not by the construction of a perfectly secure channel but by the mathematical certainty that an eavesdropper will be detected. FTP, identify this information transmission technique, based on certain properties of physics.
