Abstract

A multi-user quantum cryptography system and method are described herein. The system comprises a relay including a quantum information server so configured as to generate quantum information communications having different wavelengths and a multiplexer so configured as to separate the different quantum information communications generated by the quantum information server by their wavelength and to supply each communication to a respective user.
