    "abstract": "We demonstrate single-photon interference over 100 km using a balanced\ngated-mode photon detector and a plug \u0026 play system for quantum key\ndistribution. The visibility with 0.1 photon/pulse was more than 80% after 100\nkm transmission. This corresponds to the fidelity of a quantum cryptography\nsystem of more than 90% and a QBER of less than 10%, satisfying the security\ncriteria.",
