Complete Quantum Communication with Security

The long-standing problem of quantum information processing is to remove the classical channel from quantum communication. Introducing a new information processing technique, it is discussed that both insecure and secure quantum communications are possible without the requirement of classical channel. Quantum cryptography [1-7] and teleportation [8] are the two important aspects of quantum communication. Wiesner [1] first realized that quantum state can be used to store data to ensure its security. Apart from security reason, the idea of using quantum state for information processing was new and it laid the foundation of modern quantum information. Bennett and Brassard, in their quantum key distribution (QKD) protocol [2], pointed out
