Single-photon scattering in giant-atom topological-waveguide-QED systems

H Zhu, XL Yin, JQ Liao - arXiv preprint arXiv:2408.14178, 2024 - arxiv.org
The giant-atom topological-waveguide-QED systems have recently emerged as a promising
platform for manipulating light-matter interactions. The combination of the multiple-point …

Nonreciprocal interaction and entanglement between two superconducting qubits

YM Ren, XF Pan, XY Yao, XW Huo, JC Zheng… - arXiv preprint arXiv …, 2024 - arxiv.org
Nonreciprocal interaction between two spatially separated subsystems plays a crucial role in
signal processing and quantum networks. Here, we propose an efficient scheme to achieve …

Engineering bound state in continuum via giant atom in photonic waveguide

X Zhang, M Zhu, Z Wang - arXiv preprint arXiv:2406.08841, 2024 - arxiv.org
The bound state in the continuum (BIC) in photonic system has been widely used in the field
of lasing and sensing. We here find the controllable BIC in an artificial giant atom-dressed …

Bound states and atomic interaction in giant atom waveguide QED with dispersive coupling

M Weng, Z Wang - arXiv preprint arXiv:2409.09373, 2024 - arxiv.org
In this paper, we investigate the bound states and the effective interaction between a pair of
giant atoms, which couples to the coupled resonator waveguide in a nested configuration …
