Abstract

The search for gravitational radiation has driven important improvements in a variety of technologies for detecting very weak forces. These improvements have renewed the interest for the problem of quantum noise reduction. The use of squeezed fields was considered by Caves' and Bondurant and Shapiro2, who showed that a squeezed state interferometer requires substantially fewer photons than does a conventional (coherent-state) interferometer to reach the standard quantum limit. This note reanalyzes the problem, pointing out the importance of the coherence properties of the squeezed fields for the evaluation of photon noise reduction3.
