Nondemolition filtering of an embedded cluster-state scar under continuous local monitoring
Ximo Wang, Xi Zhao, Xiayu Sun +6
Identifying a low-entanglement eigenstate inside a many-body spectrum and preserving it during measurement are distinct tasks. We construct an explicit local ring Hamiltonian with…
Sparse and weak-measurement certification of graph-edge entanglement in PXP scar wavepackets
Ximo Wang, Yichi Zhang, Qiwei Han +6
An imperfect many-body revival does not by itself certify the entanglement of the returning state. We give a finite-record protocol for graph-edge localizable entanglement along sc…
Möbius-Guided Diagonal-Gate Compilation with Native Multiqubit Controlled-Phase Gates on Neutral-Atom Processors
Hairuo Huang, Yanwu Gu, Chen Huang +4
Diagonal gates are ubiquitous primitives in quantum algorithms, from phase oracles, hypergraph-state preparation, and multi-control logic to Hamiltonian simulation of spin models a…
ZAP: Zoned Architecture and Performant Compiler for Field Programmable Atom Array
Chen Huang, Xi Zhao, Hongze Xu +4
The scalability of neutral-atom quantum computing is increasingly limited by a compiler--architecture challenge: logical circuits must be mapped onto dynamically reconfigurable ato…
