The influence of stochastic dispersion on quantum key distribution system (original) (raw)

Abstract

By theoretical calculation and analysis, this paper studies the influence of stochastic fiber dispersion on interference stability and erroneous detected rate of quantum key distribution (QKD) system receiver, and analyses its effects on quantum key generation rates of decoy states QKD. The result shows that the interference contrast and erroneous detected rate of the system will be affected by real part only but not by imaginary part only. However, when the real part exists, the imaginary part will have an effect on the interference contrast and erroneous detected rate.
