Optimal detection of ultra-broadband bi-photons with quantum nonlinear SU(1,1) interference

Nir Nechushtan, Hanzhong Zhang, Mallachi Meller, and Avi Pe'er

Abstract

SU(1,1) interference is a major tool for quantum detection of squeezed light. We optimize the interference visibility experimentally based on the phase matching and beam parameters. We demonstrate near-ideal visibility (loss-limited) over an octave bandwidth.
