The increasing level of experimental control over atomic and optical systems gained in
recent years has paved the way for the exploration of new physical regimes in quantum …

We analyze the coherent transport of a single photon, which propagates in a one-
dimensional coupled-resonator waveguide and is scattered by a controllable two-level …

We theoretically study how to control transport, bound states, and resonant states of a single
photon in a one-dimensional coupled-cavity array. We find that the transport of a single …

We propose and study an approach to realize quantum switch for single-photon transport in
a coupled superconducting transmission-line-resonator (TLR) array with one controllable …

We propose an efficient, nonreciprocal single-photon device that achieves single-photon
routing and frequency conversion through chiral coupling of two one-dimensional …

In this paper, we employ two two-level atoms and a Λ-type atom to connect two one-
dimensional semi-infinite coupled resonator waveguides, respectively. The first …

Single-photon scattering properties in a coupled-resonator waveguide (CRW) coupled to a
nanocavity embedded with a two-level system are investigated theoretically. Two cases are …

A resonant two-level atom doped in a one-dimensional waveguide behaves as a mirror, but
this single-atom “mirror” can only reflect single photons perfectly at a specific frequency. For …

We investigate one-dimensional Josephson junction arrays with generalized unit cells as a
circuit approach to engineer microwave band gaps. An array described by a lattice with a …

A single-photon switch is an important element for the building of scalable quantum
networks. In this paper, we propose a feasible scheme for efficient single-photon switching …
