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

Enhancing light–matter coupling at the level of single quanta is essential for numerous
applications in quantum science. The cooperative optical response of subwavelength atomic …

We propose tunable chiral bound states in a system composed of superconducting giant
atoms and a Josephson photonic-crystal waveguide (PCW), with no analog in other …

Quantum cooperativity is evident in light-matter platforms where quantum-emitter ensembles
are interfaced with confined optical modes and are coupled via the ubiquitous …

Metasurfaces mould the flow of classical light waves by engineering subwavelength patterns
from dielectric or metallic thin films. We introduce and analyse a method in which quantum …

Atomic, molecular, and optical (AMO) physics has been at the forefront of the development of
quantum science while laying the foundation for modern technology. With the growing …

Due to the recent groundbreaking developments of nanotechnologies, it became possible to
create intrinsically quantum systems able to serve as high‐directional antennas in terahertz …

We study collective “free-space” radiation properties of two distant single-layer arrays of
quantum emitters as two-level atoms. We show that this system can support a long-lived Bell …

We study chiral and nonreciprocal single-photon scattering in a chiral-giant-molecule
waveguide-QED system. Here, the giant molecule consists of two coupled giant atoms …

In superconducting quantum circuits (SQCs), chiral routing quantum information is often
realized with the ferrite circulators, which are usually bulky, lossy and require strong …
