摘要
A communication device in embodiments is a quantum key distribution device connectable to another quantum key distribution device through a quantum communication channel to share an encryption key therebetween, and includes a common processing unit, one or more individual processing units, and a distribution unit. The common processing unit outputs intermediate data based on bit information obtained by transmitting or receiving sequence of photons with the another quantum key distribution device through the quantum communication channel. Each individual processing unit generates or provides the encryption key in accordance with the intermediate data. The distribution unit distributes the intermediate data that is output from the common processing unit to two or more distribution destination that include the individual processing units.
