The realization of strong interactions between individual photons is a long-standing goal of
both fundamental and technological significance. Scientists have known for over half a …

This is a review of state-of-the-art theory and experiment of the motion of cold and ultracold
atoms coupled to the radiation field within a high-finesse optical resonator in the dispersive …

We propose how to create and manipulate one-way nonclassical light via photon blockade
in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB) …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

An as yet outstanding goal in quantum optics is the realization of fast optical nonlinearities at
the single-photon level. This would allow for the implementation of optical devices with new …

We report on the realization of an all-optical transistor by map** gate and source photons
into strongly interacting Rydberg excitations with different principal quantum numbers in an …

Photon blockade is a dynamical quantum-nonlinear effect in driven systems with an
anharmonic energy ladder. For a single atom strongly coupled to an optical cavity, we show …

The realization of an all-optical transistor, in which one “gate” photon controls a “source”
light beam, is a long-standing goal in optics. By stop** a light pulse in an atomic ensemble …

We propose a novel scheme for the preparation of a maximally entangled state of two atoms
in an optical cavity. Starting from an arbitrary initial state, a singlet state is prepared as the …
