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

The dipole approximation is usually employed to describe light-matter interactions under
ordinary conditions. With the development of artificial atomic systems,'giant atom'physics is …

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 …

We study the generation of quantum entanglement between two giant atoms coupled to a
one-dimensional waveguide. Since each giant atom interacts with the waveguide at two …

Quantum optics with giant atoms has provided a new paradigm to study photon scatterings.
In this work, we investigate the nontrivial single-photon scattering properties of giant atoms …

Giant atoms that interact with real-space waveguides at multiple spatial points have attracted
extensive attention due to their unique interference effects. Here we propose a feasible …

In quantum optics, it is common to assume that atoms are pointlike objects compared to the
wavelength of the electromagnetic field they interact with. However, this dipole …

Engineering light-matter interactions at the quantum level has been central to the pursuit of
quantum optics for decades. Traditionally, this has been done by coupling emitters, typically …

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 …

We investigate the non-Markovian dynamics of two giant artificial atoms interacting with a
continuum of bosonic modes in a one-dimensional (1D) waveguide. Based on the …
