We report on the experimental realization of a ten-photon Greenberger-Horne-Zeilinger state using thin BiB₃O₆ crystals. The observed fidelity is 0.606±0.029, demonstrating a genuine entanglement with a standard deviation of 3.6 σ. This result is further verified using p-value calculation, obtaining an upper bound of 3.7×10⁻³ under an assumed hypothesis test. Our experiment paves a new way to efficiently engineer BiB₃O₆ crystal-based multi-photon entanglement systems, which provides a promising platform for investigating advanced optical quantum information processing tasks such as boson sampling, quantum error correction and quantum-enhanced measurement.
