Enhancing the coherence time of a neutral atom by an optical quartic trap
Haobo Chang, Zhuangzhuang Tian, Xin Lv +7
The coherence time of an optically trapped neutral atom is a crucial parameter for quantum technologies. We found that optical dipole traps with higher-order spatial forms inherent…

Resolved Raman sideband cooling of a single optically trapped cesium atom
Zhuangzhuang Tian, Haobo Chang, Xin Lv +6
We developed a resolved Raman sideband cooling scheme that can efficiently prepare a single optically trapped cesium (Cs) atom in its motional ground states. A two-photon Raman pro…

Extending the coherence time limit of a single-alkali-atom qubit by suppressing phonon-jumping-induced decoherence
Zhuangzhuang Tian, Haobo Chang, Xin Lv +6
In the fields of quantum metrology and quantum information processing with the system of optically trapped single neutral atoms, the coherence time of qubit encoded in the electron…
