    "abstract": "We propose a scheme to explore two-photon high-dimensional entanglement\nassociated with a transverse pattern by means of two-photon interference in a\nbeamsplitter. We find that the topological symmetry of the angular spectrum of\nthe two-photon state governs the nature of the two-photon interference. We\nprove that the anti-coalescence interference is the signature of two-photon\nentanglement. On the basis of this feature, we propose a special Mach-Zehnder\ninterferometer incorporated with two spiral phase plates which can change the\ninterference from a coalescence to an anti-coalescence type only for a\ntwo-photon entangled state. The scheme is simple and straightforward compared\nwith the test for a Bell inequality.",
