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…
