    "abstract": "We present two experiments testing the hypothesis of noncontextual hidden\nvariables (NCHV\u0027s). The first one is based on observation of two-photon\npseudo-Greenberger-Horne-Zeilinger correlations, with two of the originally\nthree particles mimicked by the polarization degree of freedom and the spatial\ndegree of freedom of a single photon. The second one, a single-photon\nexperiment, utilizes the same trick to emulate two particle correlations, and\nis an \"event ready\" test of a Bell-like inequality, derived from the\nnoncontextuality assumption. Modulo fair sampling, the data falsify NCHV\u0027s.",
