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

Photonic nanostructures provide a means of tailoring the interaction between light and
matter and the past decade has witnessed tremendous experimental and theoretical …

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

Strong non-linear interactions between photons enable logic operations for both classical
and quantum-information technology. Unfortunately, non-linear interactions are usually …

Single-photon detection is a requisite technique in quantum-optics experiments in both the
optical and the microwave domains. However, the energy of microwave quanta are four to …

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 …

Epitaxial quantum dots formed by III–V compound semiconductors are excellent sources of
non-classical photons, creating single photons and entangled multi-photon states on …

Engineering the electromagnetic environment of a quantum emitter gives rise to a plethora
of exotic light-matter interactions. In particular, photonic lattices can seed long-lived atom …

We develop a scattering theory to investigate the multiphoton transmission in a one-
dimensional waveguide in the presence of quantum emitters. It is based on a path integral …

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 …
