    "abstract": "We show that very large nonlocal nonlinear interactions between pairs of\ncolliding slow-light pulses can be realized in atomic vapors in the regime of\nelectromagnetically induced transparency. These nonlinearities are mediated by\nstrong, long-range dipole--dipole interactions between Rydberg states of the\nmulti-level atoms in a ladder configuration. In contrast to previously studied\nschemes, this mechanism can yield a homogeneous conditional phase shift of pi\neven for weakly focused single-photon pulses, thereby allowing a deterministic\nrealization of the photonic phase gate.",
