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 …

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

The goal of integrated quantum photonics is to combine components for the generation,
manipulation, and detection of nonclassical light in a phase-stable and efficient platform …

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 …

It has long been recognized that atomic emission of radiation is not an immutable property of
an atom, but is instead dependent on the electromagnetic environment and, in the case of …

We demonstrate a superconducting artificial atom with strong unidirectional coupling to a
microwave photonic waveguide. Our artificial atom is realized by coupling a transmon qubit …

In quantum-optics experiments with both natural and artificial atoms, the atoms are usually
small enough that they can be approximated as pointlike compared to the wavelength of the …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Superconducting qubits in a waveguide have long-range interactions mediated by photons
that cause the emergence of collective states. Destructive interference between the qubits …
