    "abstract": "We demonstrate the decoy-state quantum key distribution (QKD) with one-way\nquantum communication in polarization space over 102km. Further, we simplify\nthe experimental setup and use only one detector to implement the one-way\ndecoy-state QKD over 75km, with the advantage to overcome the security\nloopholes due to the efficiency mismatch of detectors. Our experimental\nimplementation can really offer the unconditionally secure final keys. We use 3\ndifferent intensities of 0, 0.2 and 0.6 for the pulses of source in our\nexperiment. In order to eliminate the influences of polarization mode\ndispersion in the long-distance single-mode optical fiber, an automatic\npolarization compensation system is utilized to implement the active\ncompensation.",
