Abstract

A six-user quantum key distribution over a bus network spanning a total distance 30km of standard telecommunication-grade fiber is demonstrated. Each user on the network has one unique address wavelength channel for establishing secure quantum cryptographic keys with a central network server. The address wavelengths are all in the C-band region of between 1553 nm and 1557 nm, making the system compatible with present fiber-optic communication network infrastructures. The quantum bit error rate measurements made on the network agree favorably with theoretically calculated values.
