    "abstract": "We demonstrate a scheme to spectrally manipulate a collinear, continuous\nstream of time and energy entangled photons to generate beamlike,\nbandwidth-limited fuxes of polarization-entangled photons with\nnearly-degenerate wavelengths. Utilizing an ultrashort-pulse shaper to control\nthe spectral phase and polarization of the photon pairs, we tailor the shape of\nthe Hong-Ou-Mandel interference pattern, demonstrating the rules that govern\nthe dependence of this interference pattern on the spectral phases of the\nphotons. We then use the pulse shaper to generate all four polarization Bell\nstates. The singlet state generated by this scheme forms a very robust\ndecoherence-free subspace, extremely suitable for long distance fiber-optics\nbased quantum communication.",
