e/Quantum amplifier

Information
has gloss	eng: In physics, the term quantum amplifier may refer to any device, which use some non-classical (quantum) effects for amplification of signal. In this sense, the active element of an optical laser can be considered as quantum amplifier. The weak light from a coherent optical communication system needs to be amplified before application. Therefore, the optical re-transmitters usually include quantum amplifiers.
