    "abstract": "We consider a model of quantum measurement built on an ideal operational\namplifier operating in the limit of infinite gain, infinite input impedance and\nnull output impedance and with a feddback loop. We evaluate the intensity and\nvoltage noises which have to be added to the classical amplification equations\nin order to fulfill the requirements of quantum mechanics. We give a\ndescription of this measurement device as a quantum network scattering quantum\nfluctuations from input to output ports.",
