High-fidelity entanglement swapping and generation of three-qubit GHZ state using asynchronous telecom photon pair sources

Yoshiaki Tsujimoto, Motoki Tanaka, Nobuo Iwasaki +7

We experimentally demonstrate a high-fidelity entanglement swapping and a generation of the Greenberger-Horne-Zeilinger~(GHZ) state using polarization-entangled photon pairs at tel…
