| Abstract: | This paper introduces the principle and experiment of using optical system to realize me quantum cipher communication. It first illustrates the wave-particle dualism of photon and quantum entangle effect with the double-slit quantum interference experiment. Then it briefly discusses the entangle photon parity and Bell inequality. Furthermore, it focuses on introducing the process of BB84 and B92 protocols, quantum key distribution and quantum teleportation, Finally, this article analyzes the current situation of the experimental development and its prospect in exploitation. |
