Quantum noise is any noise arising from quantum mechanical phenomena such as field quantization or the uncertainty principle. Quantum noise differs from classical noise fundamentally not only in the kinds of phenomena from which it arises, but also in key characteristic features such as its spectral density and temperature dependence.
