Abstract
Quantum Key Distribution (QKD) is the most prominent and the most mature application of quantum communications. It provides a way for two trusted users, usually named Alice and Bob, once they are provided with a public quantum channel and a public but authenticated classical channel, to exchange a secret key with a security based, not on computational assumptions as it is currently the case with classical cryptography, but on the laws of Physics, and hence, protects even against unbounded adversaries. Combined with a perfectly secure encryption scheme, QKD allows for secure message transmission with information-theoretic security.
