Partial projected ensembles reveal slow tilt-constrained information spreading
Yi-Rui Zhang, Yu-Jun Zhao, Han-Ze Li +1
Projected ensembles reveal information about quantum many-body dynamics beyond the reduced density matrix. Here we investigate how spatial constraints affect the emergence of this…
Practical Error Suppression and Mitigation for Reliable Quantum Computing
Han-Ze Li, Mengjie Yang, Xianquan Yan +3
Quantum computing is entering a transitional regime between noisy intermediate-scale quantum (NISQ) processing and early fault-tolerant quantum computation (FTQC), in which increas…
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…
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…
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…
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…
Quantum feedback induced entanglement relaxation and dynamical phase transition in monitored free fermion chains with Wannier-Stark ladder
Xuyang Huang, Han-Ze Li, Yu-Jun Zhao +2
In recent years, measurement induced entanglement transitions (MIETs) have attracted significant attention. However, the dynamical transition associated with the feedback induced s…
Fate of pseudo mobility-edge and multiple states in non-Hermitian Wannier-Stark lattice
Yu-Jun Zhao, Han-Ze Li, Xuyang Huang +2
The interaction between non-reciprocity and disorder-free localization has emerged as a fascinating open question. Here, we explore the effects of pseudo mobility edges (MEs) along…
Fate of non-Hermitian free fermions with Wannier-Stark ladder
Han-Ze Li, Minhui Wan, Jian-Xin Zhong
The Wannier-Stark localization dynamically alters the entanglement behavior of non-Hermitian free fermions. Utilizing the single-particle correlation matrix technique, we analyze t…
Quantum phase transition and critical behavior between the gapless topological phases
Hao-Long Zhang, Han-Ze Li, Sheng Yang +1
The phase transition between gapped topological phases represents a class of unconventional criticality beyond the Landau paradigm. However, recent research has shifted attention t…
