The security of quantum key distribution relies on the principles of quantum theory and its successful implementation requires the development of quantum optical techniques.
Abstract
Two parties can communicate in secret if they already share a sufficient quantity of secret information. The problem then is how to distribute this secret information or key. Quantum cryptography provides the potential to ensure the security of the process of key distribution and hence to guarantee the covert nature of the communication. The security of quantum key distribution relies on the principles of quantum theory and its successful implementation requires the development of quantum optical techniques.
