We study three-photon quantum interference and entanglement using beam splitters, revealing scattering statistics influenced by distinguishability, mixedness, and symmetry. Furthermore, genuine tripartite-entangled states are generated, achieving up to (87.3±1.1)% fidelity, with implications for photonic quantum technologies.
