I will discuss integration of control hardware into ion trap devices, specifically focusing on our recent work using planar-fabricated integrated waveguide optics to drive multi-ion quantum logic with fidelities competitive with the highest achieved to date . The optics architecture demonstrated offers a route to scaling and, as we show, simultaneously enhances stability. Aside from its relevance to quantum information processing, I will discuss how it further allows generation of optical field profiles enabling new physical operations, new photonics motivated by atomic systems, and possibilities for such techniques to advance future experiments in areas including sensing and precision metrology.
