Multi-party Agile QKD Network with a Fiber-based Entangled Source

Not Accessible

Your library or personal account may give you access

Abstract

A multi-party quantum key distribution scheme is experimentally demonstrated by utilizing a poled fiber-based broadband polarization-entangled source and dense wavelength-division multiplexing. Entangled photon pairs are delivered over 40-km of fiber, with secure key rates of more than 20 bits/s observed.
