    "abstract": "We analyze the application of bright reference pulses to prevent the\nphoton-number-splitting attack in weak-pulse quantum key distribution. Under\nthe optimal eavesdropping strategy as far as we know, the optimal parameters of\nbright reference and signal pulses can ensure a secure transmission distance up\nto 146 km. To realize the quantum key distribution scenario with up-present\ntechniques, we present an experimentally feasible scheme to create a large\nsplitting ratio between bright reference and signal pulses, and to switch the\nbright reference pulses away from signal pulses to avoid the after-pulse\ndisturbance.",
