Geometry-resolved suppression of patch-potential heating in skeleton-electrode ion traps
Published on 2026-06-02 by Chon-Teng Belmiro Chu, Hao-Chung Chen, Ting Hsu, Hsiang-Yu Lo, Ming-Shien Chang and Guin-Dar Lin @IOP SCIENCE
Abstract: We present a quantitative, geometry-resolved framework to evaluate the effects of patch-potential noise in realistic three-dimensional Paul-trap structures. As a concrete application, we analyze a skeleton-electrode architecture and compare its performance against a conventional blade trap under identical ion-to-electrode distances and matched confinement parameters. The skeleton geometry achieves a suppression of motional heating exceeding 50%, with heating rate ratios of for the axial mode and[...]
Our summary: A geometry-resolved framework evaluates patch-potential noise in Paul-trap structures. The skeleton-electrode architecture reduces motional heating by over 50% compared to conventional designs. Heating maps reveal noise contributions primarily from surfaces within 500 µm, guiding effective electrode reconfiguration strategies.
