RT Journal Article T1 Multimode quantum analysis of an interferometerwith moving mirrors A1 Luis Aina, Alfredo A1 Sánchez Soto, Luis Lorenzo AB A multimode quantum analysis of noise reduction in interferometric measurements is presented. A unitary transformation relating the output modes with the input ones for a Michelson interferometer with moving mirrors is given. The evaluation of the noise spectrum shows that with a proper choice of the input states, the sensitivity of the interferometer can be pushed beyond the standard quantum limit. The results are compared with a semiclassical analysis.
