Quantum Key Distribution

Chapter
Part of the Lecture Notes in Physics book series (LNP, volume 797)

Abstract

In this chapter a complete QKD protocol is presented, starting from the transmission via the quantum channel up to the communication over the public channel. The protocol described here is the BB84 protocol, named after Bennett and Brassard [5]. There are other protocols like the B92 protocol [3], the six-state protocol [8], the SARG protocol [19] and the Ekert protocol [10], which are not discussed here. We are focusing on BB84, the most known QKD protocol.
