Monolithic segmented blade ion trap system

Quadrupole-based traps are versatile tools for AMO research and specifically for the ion-trapping community widely used in quantum computing, simulation, and sensing. Despite the advances of planar chip microfabricated traps, three-dimensional blade traps still offer the advantages of ease of use (simpler controls), eV-deep trapping potentials, robustness to stray fields, larger ion-electrode distance (low 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, potentially more elaborate design, and better manufacturability and repeatability. Here we present our progress in assembling a compact trapping system based on a monolithic blade trap. We present the design of the trap manufactured by Translume Inc. and its characterization, as well as the surrounding vacuum and optical systems of the first prototype. Preliminary measurements show promising performance and support further development and implementation of this novel type of blade traps.
