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…
Robust controlled-Z gate for Rydberg atoms based on level-crossing-free echoing rapid adiabatic passage
Yichi Zhang, Zhenqi Bai, Xu Zhao +3
We propose a controlled-Z gate scheme for Rydberg atoms based on level-crossing-free echoing rapid adiabatic population transfer. We design antisymmetric Rabi frequency pulses and…
High-fidelity multiqubit gates with Rydberg atoms via level-crossing-free Rapid adiabatic passage
Yichi Zhang, Ximo Wang, Zhenqi Bai +2
We propose a rapid adiabatic passage (RAP) scheme based on level-crossing-free pulses for deterministic generation of multiqubit entangled states in Rydberg atom systems. Unlike co…
Parametric resonance and nonlinear dynamics in a coupled double-pendulum system
Yusheng Niu, Yixian Liu, Hongyan Fan +2
Nonlinear dynamics plays a significant role in interdisciplinary fields spanning biology, engineering, mathematics, and physics. Under small-amplitude approximations, certain nonli…
Strongly Coupled Continuous Time Crystal
Ximo Wang, Qiwei Han, Zhenqi Bai +2
Time crystals are classified into discrete time crystals and continuous time crystals based on whether they spontaneously break time-translation symmetry. Continuous-time crystals…
Geometric Quantum Gates of Non-closed Paths Under Counterdiabatic Driving
Ximo Wang, Hongyan Fan, Zhengqi Bai +1
Non-adiabatic and non-closed evolutionary paths play a significant role in the fidelity of quantum gates. We propose a high-fidelity quantum control framework based on the quasi-to…
Ultrafast creation of overlapping Rydberg electrons in an atomic BEC and Mott-insulator lattice
Michiteru Mizoguchi, Yichi Zhang, Masaya Kunimi +13
An array of ultracold atoms in an optical lattice (Mott insulator) excited to a state where single electron wave-functions spatially overlap would represent a new and ideal platfor…
