Realization of a chip-based hybrid trapping setup for ${}^{87}$Rb atoms and Yb${}^{+}$ Ion crystals

Abstract

Hybrid quantum systems integrate laser-cooled trapped ions and ultracold quantum gases within a single experimental configuration, offering vast potential for applications in quantum chemistry, polaron physics, quantum information processing, and quantum simulations. In this study, we introduce the development and experimental validation of an ion trap chip that incorporates a flat atomic chip trap directly beneath it. This innovative design addresses specific challenges associated with hybrid atom-ion traps by providing precisely aligned and stable components, facilitating independent adjustments of the depth of the atomic trapping potential and the positioning of trapped ions. Our findings include successful loading of the ion trap with linear Yb${}^{+}$ ion crystals and the loading of neutral ${}^{87}$Rb atoms into a mirror magneto-optical trap (mMOT)
