Quantum cryptography is the use of quantum existence state as the key of information encrption and decryption, the principle is the Einstein called "mysterious long distance activities" quantum entangled state. It is a quantum mechanical phenomenon, regardless of the distance between the two particles far, a particle changes will affect another particle, compared with the traditional password technology has a higher level of security. Quantum cryptography is a research hotspot of international academia in recent years. We introduce quantum key distribution, quantum commitment, bounded quantum storage model, position based quantum cryptography and post-quantum cryptography.
