Abstract: P01.00005 : Phase-sensitive amplification and SU(1,1) interferometry via multimode four-wave mixing*
J. Sam Cross

These findings have obvious applications in the simplification of quantum optical experiments that involve the generation or amplification of more than two correlated modes. Additionally, we describe how this result may be employed in a “touchless” or interaction-free SU(1,1) interferometry scheme, wherein a phase measurement may be made remotely on a pair of modes without introducing loss or destroying any squeezing between them.
