Defect-free arbitrary-geometry assembly of mixed-species atom arrays
Cheng Sheng, Jiayi Hou, Xiaodong He +8
Optically trapped mixed-species single atom arrays with arbitrary geometries are an attractive and promising platform for various applications, because tunable quantum systems with…
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…
High Fidelity Single-qubit Gates of a Single Neutral Atom in the Magic-Intensity Optical Dipole Trap
Cheng Sheng, Xiaodong He, Ruijun Guo +6
We demonstrate high fidelity single-qubit gate operation in a trapped single neutral atom. The atom is trapped in the recently invented magic-intensity optical dipole trap (MI-ODT)…
Coherence preservation of a single neutral atom qubit transferred between magic-intensity optical traps
Jiaheng Yang, Xiaodong He, Ruijun Guo +7
We demonstrate that the coherence of a single mobile atomic qubit can be well preserved during a transfer process among different optical dipole traps (ODTs). This is a prerequisit…
