This review describes the emerging field of waveguide quantum electrodynamics concerned
with the interaction of photons propagating in a waveguide with localized quantum emitters …

This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

A central goal within quantum optics is to realize efficient, controlled interactions between
photons and atomic media. A fundamental limit in nearly all applications based on such …

Quantum light–matter interfaces are at the heart of photonic quantum technologies.
Quantum memories for photons, where non-classical states of photons are mapped onto …

Considerable efforts have been recently devoted to combining ultracold atoms and
nanophotonic devices,,–to obtain not only better scalability and figures of merit than in free …

Atoms interact with each other through the electromagnetic field, creating collective states
that can radiate faster or slower than a single atom, ie, super-and sub-radiance. When the …

Optical quantum memory is an essential element for long-distance quantum communication
and photonic quantum computation protocols. The practical implementation of such …

We report experimental observations of a large Bragg reflection from arrays of cold atoms
trapped near a one-dimensional nanoscale waveguide. By using an optical lattice in the …

Photons in a nonlinear medium can repel or attract each other, resulting in strongly
correlated quantum many-body states,. Typically, such correlated states of light arise from …
