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

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

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 …

Isolating single molecules in the solid state has allowed fundamental experiments in basic
and applied sciences. When cooled down to liquid helium temperature, certain molecules …

Nanophotonics offers opportunities for engineering and exploiting the quantum properties of
light by integrating quantum emitters into nanostructures, and offering reliable paths to …

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 …

Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

Conventional spectroscopy uses classical light to detect matter properties through the
variation of its response with frequencies or time delays. Quantum light opens up new …

Strong non-linear interactions between photons enable logic operations for both classical
and quantum-information technology. Unfortunately, non-linear interactions are usually …

Molecular potential energy surfaces can be actively manipulated by light. This is usually
done by strong classical laser light but was recently demonstrated for the quantum field in an …
