High fidelity entanglement of neutral atoms via a Rydberg-mediated single-modulated-pulse controlled-PHASE gate
Zhuo Fu, Peng Xu, Yuan Sun +8
Neutral atom platform has become an attractive choice to study the science of quantum information and quantum simulation, where intense efforts have been devoted to the entangling…
Influence of ground-Rydberg coherence in two-qubit gate based on Rydberg blockade
Yangyang Liu, Yuan Sun, Zhuo Fu +5
For neutral atom qubits, the two-qubit gate is typically realized via the Rydberg blockade effect, which hints about the special status of the Rydberg level besides the regular qub…
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…
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…
United test of the equivalence principle at level using mass and internal energy specified atoms
Lin Zhou, Chuan He, Si-Tong Yan +14
We use both mass and internal energy specified rubidium atoms to jointly test the weak equivalence principle (WEP). We improve the four-wave double-diffraction Raman transition met…
