Towards a continuously reloadable Yb-Rb Rydberg atom array

Rydberg atom array architectures have progressed immensely in recent years, enabling ever larger system sizes, efficient qubit encoding, and fast, coherent control of logical operations. Despite their successes in quantum computation and simulation, error correction remains an outstanding challenge, driving efforts to implement mid-circuit measurements and continuous atom loading. To meet this challenge, we are developing a dual-species atom array platform that combines an alkali element (rubidium-87) with an alkaline-earth-like element (ytterbium-171) and features continuous reloading of both species. A dual-species architecture offers more complex inter-atomic interactions while maintaining selective control and readout of each atomic species. These dual-species advantages, combined with the trappability of Yb in the Rydberg state, make our platform well-suited to mid-circuit measurements. Our design features two distinct regions, so that the initial cooling and trapping of each species in a 3D magneto-optical trap is spatially separated from the main science region of the glass cell. This will allow uninterrupted quantum operations in the atom array while new atoms are captured, initialized, and transported to a reservoir adjacent to the computation area via a running-wave optical lattice. The strategic choice of elements and the ability to continuously introduce new atoms during operations will enable the efficient creation, control, and measurement of entangled quantum states, allowing for more sophisticated quantum information processing and quantum simulation tasks. We report on our completed vacuum chamber assembly, 3D MOTs for each element, and progress towards continuous reloading.
