Lecture

Quantum Key Distribution: BB84

Description

This lecture covers Quantum Key Distribution (QKD) and the BB84 protocol, focusing on generating a one-time pad for secure communication. The goal is to create a common secret between two parties, A and B, using quantum communication. The instructor explains the primitive protocols, such as Denne Coding and Teleportation, and the application of Bell inequalities to QKD. The lecture delves into the process of transmitting and encoding information to establish a secure key. Various scenarios are discussed, including the presence of an eavesdropper (Eve) and the methods to ensure the secrecy of the generated key.
