According to one embodiment, a multiplexing device includes a multiplexing circuitry, a branching circuitry, a light receiving circuitry, and a processor. The multiplexing circuitry performs optical wavelength multiplexing on quantum signals transmitted from a plurality of quantum key distribution (QKD) devices. The branching circuitry branches an optical wavelength multiplexed quantum signal into a quantum signal to be measured and a quantum signal to be output to external at a predetermined branching ratio. The light receiving circuitry measures intensity of the quantum signal to be measured to acquire a measurement result. The processor adjusts intensity of the quantum signal output from each of the plurality of QKD devices based on the measurement result and the predetermined branching ratio.
