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

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 coherent single-photon scattering in a one-dimensional waveguide coupled to
a giant artificial molecule consisting of two coupled giant atoms. Since each giant atom …

We propose a single-photon router using a single atom with an inversion center coupled to
quantum multichannels made of coupled-resonator waveguides. We show that the …

The waveguide quantum electrodynamics (QED) system may have important applications in
quantum device and quantum information technology. In this article we review the methods …

Coherent photon-emitter interfaces offer a way to mediate efficient nonlinear photon-photon
interactions, much needed for quantum information processing. Here we experimentally …

The routing capability is a requisite in quantum network. Although the quantum routing of
signals has been investigated in various systems both in theory and experiment, the general …

Quantum routers are the necessary elements of the quantum information network, and thus
their routing capabilities are particularly important. With the atomic mirrors robustly …

We develop a general dynamical theory for studying a single-photon transport in a one-
dimensional (1D) waveguide coupled to multiple emitters which can be either identical or …

We propose a single-photon frequency converter via a one-dimensional waveguide coupled
to a three-level V-type atom. An on-demand classical driving field is used to couple to the …
