| contents | Rydberg atoms as versatile tools for quantum applications are extremely sensitive to electric fields. When utilizing these atoms, it becomes imperative to comprehensively characterize and mitigate any residual electric fields present in the environment. Particularly for single Rydberg atoms trapped in optical tweezers in a compact quartz vacuum cell, we have identified that a significant source of background electric fields originates from electrons bound to the cell surface. These electrons are generated by the 297-nm light used for single-photon Rydberg excitation. Furthermore, once the electrons are desorbed from the surface through exposure to ultraviolet light, the incoherent ground-Rydberg transition undergoes a transformation into coherent excitation, since the noise of residual electric fields are effectively mitigated. Our studies promote enhanced control and reliable performance of Rydberg atom-based systems, thereby paving the way for advancements in quantum information processing, the realization of high-fidelity quantum gates, and the development of precise quantum sensors. |
