Demonstration of a new integrated photonics architecture using Ba+ ions

Oral

Abstract

Scalable trapped-ion quantum computing benefits from multi-wavelength, compact optical systems near the trap. We demonstrate a novel integrated photonics architecture incorporating a 3D microfabricated mirror and benchmark its performance using single barium ions. Because Ba+ uses visible wavelengths, it is well-suited for multi-wavelength integrated optics. Furthermore, ion sensitivity allows for characterization of stray fields and their impact on trapping stability. Together, these measurements provide an initial characterization of the 3D-printed mirror and its influence on the local trapping environment.
