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…

Preparation of a Heteronuclear Two-atom System in the 3D Motional Ground State in an Optical Tweezer
Kunpeng Wang, Xiaodong He, Ruijun Guo +7
We report the realization of a heteronuclear two-atom of Rb-Rb in the ground state of an optical tweezer (OT). Starting by trapping two different isotopic single atom…
