Quantum Cryptography is based upon the use of quantum effects and extends those effects for conventional cryptographic methods. The two major advantages of quantum cryptography over conventional cryptography are true random secret key generation and eavesdropping detection. Quantum cryptography has been developed which promises more secure communication than any existing technique and cannot be compromised by quantum computers. Cryptography is the art of encoding and decoding messages and has existed as long as people have distrusted each other and sought forms of secure communication.
