| Description | This thesis investigates the integration of microcavities into linear Paul traps as a critical step toward scalable trapped-ion quantum computing. While trapped ions offer high-fidelity operations and long coherence times, scaling to the large qubit numbers required for fault-tolerant computation presents significant challenges. Efficient photonic interconnects, essential for modular architectures like MUSIQC, can be made possible with an efficient ion-cavity interface. Specifically, a microcavity of length of a few hundred micrometers is desired. To this end, we designed, fabricated, and characterized a miniaturized linear trap compatible with the microcavity integration. We addressed technical barriers such as RF potential distortion from cavity shields, and show that the effect can be suppressed by shield design and enable single-RF driving. In addition, we analyze the impact of dielectric charging on secular frequency shifts and propose a correction method for stray electric fields. This work advances both the theoretical understanding and practical implementation of cavity-integrated ion traps, laying the groundwork for robust, modular trapped-ion quantum processors. | |||||||
