Abstract
We propose a quantum-nondemolition measurement of the amplitude quadra ture and the photon-number statistics by using the effect of radiation pressure on a freely suspended mirror. We propose to measure the mome ntum fluctuations of the mirror which will give us a readout of the am plitude quadrature fluctuations. The scheme we propose is able to avoi d the back-action noise leaving the state of the field after the measu rement practically undegraded.
