Out of equilibrium quasiparticles (QPs) are one of the main sources of decoherence in
superconducting quantum circuits and one that is particularly detrimental in devices with …

A generalized quantum Rabi Hamiltonian with both one-and two-photon terms has emerged
in the circuit quantum electrodynamics system for a decade. The usual parity symmetry is …

In this work, we investigate the nonperturbative decay dynamics of a quantum emitter
coupled to a composite right-/left-handed transmission line. Our theory captures the …

Maturing hybrid circuit quantum electrodynamics architectures composed of semiconductor
quantum dots and on-chip microwave resonators promise an effective approach for quantum …

We propose a scheme to realize a novel, to the best of our knowledge, scenario that the
single-photon transport in a one-dimensional waveguide can be affected by the …

Planar superconducting microwave transmission line resonators can be operated at multiple
harmonic resonance frequencies. This allows covering wide spectral regimes with high …

We investigate the entanglement transfer between giant atoms in waveguide-QED systems.
The system consists of two pairs of two-level giant atoms, $ ab $ and $ cd $, each …

By consistently applying the formalism of quantum electrodynamics, we developed a
comprehensive theoretical framework describing the interaction of single microwave …
