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 …

Two decades after their demonstration, superconducting nanowire single-photon detectors
(SNSPDs) have become indispensable tools for quantum photonics as well as for many …

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

Synthesizing many-body quantum systems with various ranges of interactions facilitates the
study of quantum chaotic dynamics. Such extended interaction range can be enabled by …

Abstract Models of light–matter interactions in quantum electrodynamics typically invoke the
dipole approximation,, in which atoms are treated as point-like objects when compared to …

Waveguide QED simulators are analog quantum simulators made by quantum emitters
interacting with one-dimensional photonic band gap materials. One of their remarkable …

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 …

While designing the energy-momentum relation of photons is key to many linear, nonlinear,
and quantum optical phenomena, a new set of light-matter properties may be realized by …

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 …
