    "abstract": "We present a detailed analysis of a new robust quantum repeater architecture\nbuilding on the original DLCZ protocol [L.M. Duan \\textit{et al.}, Nature\n(London) \\textbf{414}, 413 (2001)]. The new architecture is based on two-photon\nHong-Ou-Mandel-type interference which relaxes the long-distance\ninterferometric stability requirements by about 7 orders of magnitude, from\nsub-wavelength for the single photon interference required by DLCZ to the\ncoherence length of the photons, thereby removing the weakest point in the DLCZ\nschema. Our proposal provides an exciting possibility for robust and realistic\nlong-distance quantum communication.",
