Reframing SU(1,1) interferometry

Presented by Carlton Caves, University of New Mexico

SU(1,1) interferometry takes advantage of the reduced noise in the correlations of two-mode squeezed states. I will recast SU(1,1) interferometry as a way of making simultaneous back-action-evading measurements of both components of the displacement of a harmonic oscillator, exactly equivalent to measuring the two displacement components on separate modes subjected to the same displacement. I will then discuss how the same correlations can be used in two scenarios not usually thought of in terms of SU(1,1) interferometry: quantum illumination and characterization of the linear-optical network in randomized boson sampling.
