Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

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 …

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 …

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 …

We demonstrate a quantum nanophotonics platform based on germanium-vacancy (GeV)
color centers in fiber-coupled diamond nanophotonic waveguides. We show that GeV …

We introduce a general model for a network of quantum sensors, and we use this model to
consider the following question: When can entanglement between the sensors, and/or …

Rydberg atoms with principal quantum number n⪢ 1 have exaggerated atomic properties
including dipole-dipole interactions that scale as n 4 and radiative lifetimes that scale as n 3 …

The integration of nanophotonics and atomic physics has been a long-sought goal that
would open new frontiers for optical physics, including novel quantum transport and many …

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 …
