Scalable ion-trapping system for quantum technology applications

Paul traps are versatile tools for AMO research and specifically for the ion-trapping community, which is widely used in quantum computing, simulation, networks, and sensing. With the vast progress of these fields in recent years, it becomes increasingly evident that further advancement may benefit from a standardized, reliable, and highly scalable ion-trapping system, especially for sensing and networking applications, where a large number of such systems may be needed. Here, we present the development of the next generation of compact, highly versatile, yet simple ion-trapping systems based on a monolithic blade trap. Three-dimensional blade traps offer the advantages of ease of use (simpler controls), eV-deep trapping potentials, robustness to stray fields, larger ion-electrode distance (thus lower heating rates), as well as wider and multi-directional optical access. A monolithic, segmented blade trap represents further advancement in the blade trap design as it offers better structural accuracy by eliminating the need for manual alignment, a compact structure, a potentially more elaborate design, and better manufacturability and repeatability. We demonstrate the design of the trap manufactured by Translume Inc., its characterization, and the surrounding vacuum and optical systems of this prototype, as well as testing of the complete system that was independently performed on two separate assemblies. Preliminary measurements show promising performance and support further development and implementation of this novel design. We will also present the conceptual design of next-generation ion trapping systems featuring further miniaturization of the vacuum envelope as well as the optical layer and other peripheral components. This compact design is less sensitive to environmental conditions and more suitable for aerospace applications.
