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

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

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

Parity-time (PT) symmetric periodic structures, near the spontaneous PT-symmetry breaking
point, can act as unidirectional invisible media. In this regime, the reflection from one end is …

Abstract The Jaynes‐Cummings model describes the coupling between photons and a
single two‐level atom in a simplified representation of light‐matter interactions. In circuit …

We study the collective effects that emerge in waveguide quantum electrodynamics where
several (artificial) atoms are coupled to a one-dimensional superconducting transmission …

We study photon-photon correlations and entanglement generation in a one-dimensional
waveguide coupled to two qubits with an arbitrary spatial separation. To treat the …

We discuss the properties of atom-photon bound states in waveguide QED systems
consisting of single or multiple atoms coupled strongly to a finite-bandwidth photonic …

We extend the input-output formalism of quantum optics to analyze few-photon transport in
waveguides with an embedded qubit. We provide explicit analytical derivations for one-and …

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 …
