Heterogenous integration and adjustable RF nodes: approaches to scaling trapped ion platforms

Trapped ion quantum computers utilize micro-fabricated surface traps for advantages in control and scaling. As these machines push from tens to hundreds of ions, integration of not only the electrical control, but the optical control is a clear scaling advantage. However, monolithic integration of photonic components into the trap can slow advances in trap designs and force species specific traps. Characterizing these devices can prove challenging when the overlap of lithographically defined waveguide light with the ion is not guaranteed. An alternative approach is to combine the technologies at the packaging level, rather than the chip level, by leveraging heterogeneous integration. We present progress towards heterogenous integration of a photonic circuit with a novel surface ion trap that additionally enables in-situ adjustment of the ion via manipulation of the RF node.
