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…
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…
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…
Quantum Mpemba effect in long-ranged U(1)-symmetric random circuits
Han-Ze Li, Ching Hua Lee, Shuo Liu +2
The Mpemba effect, where a state prepared farther from equilibrium relaxes faster to equilibrium than one prepared closer, has a quantum counterpart where relaxation is resolved by…
Measurement-Induced Entanglement Phase Transition in Free Fermion Systems
Han-Ze Li, Jian-Xin Zhong, Xue-Jia Yu
Measurement-induced entanglement phase transitions (MIET) highlight how local measurements drive quantum systems between area-law and volume-law entangled states. This review surve…
