Quantum Cryptography I

Abstract

I will present the first (and simpler) Quantum Cryptography protocol (Bennett & Brassard 1984 aka BB84). This protocol gives a way to distribute a secret key with "unconditional" security based on the laws of quantum mechanics. The presentation will be basic and assuming no prior knowledge of quantum mechanics (all relevant properties of QM will be introduced).
