Abstract: Disclosed is a communication apparatus including a synchronization signal detector configured to detect a synchronization signal received from other communication apparatus coupled to the communication apparatus, wherein the other communication apparatus sends a quantum signal generated by a first light source to the communication apparatus, and a second light source configured to generate a decoy signal to be added to a quantum signal that is to be sent to the other communication apparatus according to a result of the detection of the synchronization signal.
