Abstract
A system for sensing phase changes in a medium includes a bidirectional interferometer having a reference arm and a sensing arm, two inputs at each of the two ends of the interferometer, and a circulator disposed between each input and the interferometer. Sources provide squeezed state pulses at an input at each end of the interferometer. Spaced-apart partial reflectors are disposed along the arms. There are detectors associated with each input. The circulators pass the squeezed state pulses into the interferometer and route reflections of the pulses to the detectors. Classical pulses may provided at the other input at each end of the interferometer.
