Abstract
According to an embodiment, a QKD device includes one or more hardware processors configured to: detect a quantum signal by photons transmitted from a transmitting quantum key distribution (QKD) device; monitor monitoring information including a parameter based on the quantum signal; and transmit, to the transmitting QKD device, a switching signal for switching from a normal mode to a debug mode for enhancing intensity of the quantum signal by a predetermined value, based on the monitoring information.
