Abstract
Here an experiment is proposed to demonstrate squeezed-state enhanced interferometry. An interferometer employing differenced detection, in which the photodetectors have less than a unit quantum efficiency, is analyzed. In order to avoid low-frequency noise, a readout signal at frequency 2νs is generated at the detector by injecting coherent light having two frequency components ν0 + νs and ν0 − νs into one input port of the interferometer. In order to realize a significant sensitivity enhancement, squeezed light fed into the other input port must be squeezed at frequencies ν0 ± νs and ν0 + 3νs.
