In this context, our work introduces a compact individual addressing system leveraging four acousto-optic deflectors (AODs). This system affords improved addressing flexibility, increased laser power, and reduced crosstalk, thereby facilitating the realization of high-fidelity gates within a long ion chain. Measured results include a demonstrated addressing capability of up to 30 ions, with expected crosstalk levels below 0.1%. Furthermore, we envision achieving at least two times faster entangling gates than our current MEMS mirror steering system [2]. Additionally, our approach incorporates miniaturized optical components with minimal degrees of freedom, contributing to the development of a compact system characterized by minimal optical path length. This design choice enhances the system's resilience against external vibrations, solidifying its potential for practical quantum computing applications.
