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…

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…
