摘要

This paper proposes and analyzes a multi-user wavelength division multiplexing-quantum key distribution (WDM-QKD) network that employs a modified plug-and-play system; this system employs a multi-wavelength laser diode to generate wavelength pulses for Bobs and utilizes a single phase modulator to modulate the returned pulses for all users. Benefitting from the time delay and delay line in Bobs, the returned pulses remain independent of Rayleigh backward scattering caused by strong pulse signals. Numerical simulations and results show that the key rate per user maintains a high level compared with a point-to-point link, because the communications between Alice and four Bobs can be carried out simultaneously.
