Under fixed conditional-probe energy and fixed gain, optimized success-weighted photon subtraction, addition, and catalysis all give less Fisher information than the optimized Gaussian input in an SU(1,1) interferometer.
They varym= 1,2,3,4 with- out matching the conditional energy, so they diagnose operation order rather than a resource advantage

Heralded Non-Gaussian Squeezed-State Inputs for Parity-Detection SU(1,1) Interferometry
Under fixed conditional-probe energy and fixed gain, optimized success-weighted photon subtraction, addition, and catalysis all give less Fisher information than the optimized Gaussian input in an SU(1,1) interferometer.
