Efficient preparation of 2D defect-free atom arrays with near-fewest sorting-atom moves
Cheng Sheng, Jiayi Hou, Xiaodong He +7
Sorting atoms stochastically loaded in optical tweezer arrays via an auxiliary mobile tweezer is an efficient approach to preparing intermediate-scale defect-free atom arrays in ar…
Doppler-insensitive two-qubit controlled-PHASE gate protocol with dual-pulse off-resonant modulated driving for neutral atoms
Yuan Sun, Peng Xu, Liang Liu
For neutral atom qubits, the residual thermal motion of the cold atoms constitutes a major challenge that limits the accessible two-qubit gate fidelity. Recently, an interesting ty…
Revealing Energy Dependence of Quantum Defects via Two Heteronuclear Atoms in an Optical Tweezer
Kunpeng Wang, Xiaodong He, Xiang Gao +8
As a physically motivated and computationally simple model for cold atomic and molecular collisions, the multichannel quantum defect theory (MQDT) with frame transformation (FT) fo…
Balanced Coherence Times of Mixed-Species Atomic Qubits in a Dual Magic-Intensity Optical Dipole Trap Array
Ruijun Guo, Xiaodong He, Cheng Sheng +7
In this work, we construct a polarization-mediated magic-intensity (MI) optical dipole trap (ODT) array, in which the detrimental effects of light shifts on the mixed-species qubit…
Two-qubit controlled-PHASE Rydberg blockade gate protocol for neutral atoms via off-resonant modulated driving within a single pulse
Yuan Sun, Peng Xu, Ping-Xing Chen
Neutral atom array serves as an ideal platform to study the quantum logic gates, where intense efforts have been devoted to improve the two-qubit gate fidelity. We report our recen…
