Entanglement of up to 6 photons on a silicon photonic quantum circuit
Jong-Moo Lee, Woncheol Shin, Tae‐Wan Kim, Yongsoo Hwang · 2025
Six-photon entanglement is demonstrated on a silicon photonic circuit integrating spirals, spectral filters, and linear-optic gates for eight path-encoded qubits. The indistinguishability of photons is verified through a 97% Hong-Ou-Mandel visibility measurement.
