SUMMARY:Quantum Cryptography: Quantum Key Distribution protocols
DESCRIPTION:Quantum cryptography [BBE92] consists of the communication of a
 shared secret key between two users (Alice and Bob) which prevents an
 eavesdropper (Eve) from intercepting it without being detected\, the
 security being proven by the principles of quantum physics. These
 mechanisms are called quantum key distribution (QKD) protocols.\nIn this
 talk\, we will present the first QKD protocol proposed in 1984 by Bennet
 and Brassard [BB84]\, explaining how the protocol works and why Eve cannot
 intercept the distributed key without being detected. We will also briefly
 present another protocol proposed by Ekert in 1991 [Eke91]. This
 alternative protocol is based on the violation of Bell's inequalities with
 quantum physics\, a fact that led to the 2022 Nobel Prize in Physics for
 Alain Aspect\, John Clauser and Anton Zeilinger
 [Nobel2022].\n\n\n\nReferences:\n\n[BB84] Charles H. Bennett and Gilles
