Strong long-range interactions between Rydberg atoms give rise to an effective interaction blockade for dark-state polaritons, which results in large optical nonlinearities and modified polariton number statistics. Our work provides a better understanding of strongly-interacting dark-state polaritons and creates new avenues in the area of single photon nonlinear optics and for the generation of nonclassical states of light and matter.<\/p>\n<h3><span class=\"authors\">C.
