quantum noise: Noise attributable to the discrete and probabilistic nature of physical phenomena and their interactions. Note 1: Quantum noise represents the fundamental limit of the achievable signal-to-noise ratio of an optical communication system. This limit is never achieved in practice. [After FAA] Note 2: Examples of quantum noise are photon noise in an optical signal and shot noise in an electrical conductor or semiconductor.
