- Disclosed are a quantum information transmitter, a quantum communication system including the same, and an operating method of the quantum information transmitter. The quantum information transmitter includes a light source driver, a light source, and a light modulator. The light source driver generates a first light source driving signal having a first level and a second light source driving signal having a second level. The light source generates a first light signal having a first average number of photons in response to the first light source driving signal, and generates a second light signal having a second average number of photons in response to the second light source driving signal. The optical modulator modulates the first light signal to generate a target signal, and modulates the second light signal to generate a decoy signal.
