Abstract
A method of entangling photons in a distributed quantum-based communication system is disclosed which includes generating sets of entangled photon pairs between a plurality of remote nodes (Nodes Aand Nodes B) and a central entangling node (Node C), wherein Nodes Aand Bare in both quantum communication and classical communication with Node C, wherein one photon of a first entangled photon pair set is transmitted Node Aand one photon of a second entangled photon pair set is transmitted to Node B, each over the associated quantum channels, and performing Bell-state measurements between the other photon of the first entangled photon pair and the other photon of the second entangled photon pair, such that if the photons arrive at about same time having about same frequency, then the photon pairs are marked as being entangled.
