Abstract
The communication distance of QKD is limited by exponential attenuation of photons propagating through optical fibers. However, it has been shown that introducing a quantum repeater can improve the order of the attenuation and is useful for extending the communication distance of QKD when the repeater noise is ignored. In this paper, we analyze the effectiveness of the quantum repeater when taking the repeater noise into consideration. We analyze the effectiveness also from the viewpoint of the security and show that QKD is secure even if a quantum repeater is used.
