In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Photon-photon scattering in vacuum is extremely weak. However, strong effective
interactions between single photons can be realized by employing strong light-matter …

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 …

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 …

We propose an experimentally accessible single-photon routing scheme using a△-type
three-level atom embedded in quantum multichannels composed of coupled-resonator …

Excitation of a bound state in the continuum (BIC) through scattering is problematic since it is
by definition uncoupled. Here, we consider a type of dressed BIC and show that it can be …

We derive a full quantum optical model of interactions between a dipole and a metal
nanoparticle. The electromagnetic field of the nanoparticle is quantized from the time …

Interactions between single spins and photons are essential for quantum networks and
distributed quantum computation. Achieving spin–photon interactions in a solid-state device …

We study the disentanglement dynamics of two giant atoms coupled to a common one-
dimensional waveguide. We focus on the non-Markovian retarded effect in the …

We experimentally and theoretically investigate collective radiative effects in an ensemble of
cold atoms coupled to a single-mode optical nanofiber. Our analysis unveils the microscopic …
