Fibonacci many-body scars in a decorated Rule-54 quantum cellular automaton
Han-Ze Li, Jian-Xin Zhong
Quantum many-body scars provide a controlled form of weak ergodicity breaking, in which structured nonthermal eigenstates coexist with a thermalizing many-body spectrum. We introdu…
Universal Quantum Gate Set from Multiple-Braiding Sequences in (, ) Anyon Models
Jiangwei Long, Zihui Liu, Yizhi Li +2
We study the implementation of a universal quantum gate set via multiple-braiding within (, ) anyon models. The multiple elementary braiding matrices (ME…
A fast and exact approach for stabilizer Rényi entropy via the XOR-FWHT algorithm
Xuyang Huang, Han-Ze Li, Ching Hua Lee +1
Quantum advantage is widely understood to rely on key quantum resources beyond entanglement, among which nonstabilizerness (quantum ``magic'') plays a central role in enabling univ…
Entanglement phases and phase transitions in monitored free fermion system due to localizations
Yu-Jun Zhao, Xuyang Huang, Yi-Rui Zhang +2
In recent years, the presence of local potentials has significantly enriched and diversified the entanglement patterns in monitored free fermion systems. In our approach, we employ…
Non-Hermitian topological superfluidity in a three-dimensional fermi gas with spin-orbit coupling
Pingcheng Zhu, Lihong Zhou, Jianxin Zhong
The experimental advances in realizing artificial spin-orbit coupling (SOC) and non-Hermitian potentials in ultracold atomic system open a new avenue for exploring their significan…
Slow growth of quantum magic in disorder-free Stark many-body localization
Han-Ze Li, Yi-Rui Zhang, Yu-Jun Zhao +2
Disorder-free quantum many-body localization can strongly suppress transport while still enabling the dynamical buildup of computationally costly non-Clifford resources. In a tilte…
