    "abstract": "Polarizations of single-photon pulses have been controlled with long-term\nstability of more than 10 hours by using an active feedback technique for\nauto-compensation of unpredictable polarization scrambling in long-distance\nfiber. Experimental tests of long-term operations in 50, 75 and 100 km fibers\ndemonstrated that such a single-photon polarization control supported stable\npolarization encoding in long-distance fibers to facilitate stable one-way\nfiber system for polarization-encoded quantum key distribution, providing\nquantum bit error rates below the absolute security threshold.",
