arXiv:2611.10685v1 Announce Type: new Abstract: Machine-discovered graphs generate NOON states after heralding and output-number selection, but their interference mechanisms and optical implementations are not immediately apparent. We derive analytic weight conditions for arbitrary photon number $N$ by counting pair-generation processes that cancel mixed output occupations. These conditions yield quantum experiments by path identity using a Hong-Ou-Mandel interferometer and photon-pair sources. Takagi decomposition of the pair-amplitude matrix gives an exact Gaussian implementation using single-mode squeezers followed by a passive interferometer.
