Heralded Non-Gaussian Squeezed-State Inputs for Parity-Detection SU(1,1) Interferometry
Non-Gaussian operations can reshape the photon statistics of continuous-variable probes, but their metrological advantage is meaningful only when heralding probability and photon-number resources are counted consistently. We compare photon subtraction, photon addition, and photon catalysis as input-side heralding opera...
