Cryptography using quantum systems, which enable two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt messages, but not as a form of encryption itself. The nature of quantum cryptography is such that any attempt by eavesdroppers to ascertain the key will alert the authenticated participants of the Quantum Key Distribution scheme.
