Photonic state engineering via energy-level crossing by giant atoms in topological waveguide QED setup
Mingzhu Weng, Gang Wang, Zhihai Wang
Photonic state engineering in waveguide QED is typically based on local light-matter interactions. This limits its control over the spatial structure of bound photonic states. Here…
Liouvillian gap closing--bound states in the continuum connection and diverse dynamics in a giant-atom waveguide QED setup
Hongwei Yu, Mingzhu Weng, Zhihai Wang +1
In open quantum systems, reduced dynamics is commonly described by a master equation, whose Liouvillian gap closing (LGC) typically signals the emergence of decoherence-free subspa…
Bound state in the continuum and multiple atom state transfer applications in a waveguide QED setup
Xiang Guo, Xiaojun Zhang, Mingzhu Weng +5
Bound states in the continuum (BICs) have been extensively exploited to enhance light--matter interactions in metamaterials, yet their emergence and utility in multi-atom waveguide…
High-fidelity Generation of Bell and W States in Giant Atom System via Bound State in the Continuum
Mingzhu Weng, Hongwei Yu, Zhihai Wang
In this paper, we propose a high-fidelity scheme for generating entangled states in a system of two and three giant atoms coupled to the coupled resonator waveguide. Our approach l…
Bound states and atomic interaction in giant atom waveguide QED with dispersive coupling
Mingzhu Weng, Zhihai Wang
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 configurati…
Interaction and entanglement engineering in driven giant atoms setup with coupled resonator waveguide
Mingzhu Weng, Xin Wang, Zhihai Wang
We investigate the coherent interactions mediated by the coupled resonator waveguide between two types of giant atoms. We find that the effective coupling and collective dissipatio…
