    "abstract": "This paper reports 1.5-um band time-bin entanglement generation. We employed\na spontaneous four-wave mixing process in a dispersion shifted fiber, with\nwhich correlated photon pairs with very narrow bandwidths were generated\nefficiently. To observe two-photon interference, we used planar lightwave\ncircuit based interferometers that were operated stably without feedback\ncontrol. As a result, we obtained coincidence fringes with 99 % visibilities\nafter subtracting accidental coincidences, and successfully distributed\nentangled photons over 20-km standard single-mode fiber without any\ndeterioration in the quantum correlation.",
