An Implementation Scheme of BB84-Protocol-Based Quantum Key Distribution System

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 260)


The BB84 protocol is a secure communication solution that has been proved to be unconditionally secure. The quantum key distribution system that is based on this protocol has been gradually developed towards the application stage. This paper proposes a scheme to realize quantum key distribution system based on BB84 protocol using weak coherent light source, polarization controller and delay multiplexing detection technology to prepare single photon, to design photon polarization states orthogonal to each other, and to detect single photon respectively.
