Long-range interactions and entanglement of slow single-photon pulses
Inbal Friedler, David Petrosyan, Michael Fleischhauer, Gershon Kurizki
abstract: We show that very large nonlocal nonlinear interactions between pairs of
colliding slow-light pulses can be realized in atomic vapors in the regime of
electromagnetically induced transparency. These nonlinearities are mediated by
strong, long-range dipole--dipole interactions between Rydberg states of the
multi-level atoms in a ladder configuration. In contrast to previously studied
schemes, this mechanism can yield a homogeneous conditional phase shift of pi
even for weakly focused single-photon pulses, thereby allowing a deterministic
realization of the photonic phase gate.
