Ion trap quantum processors need two-dimensional connectivity between ions to harness their full potential [1]. We report on industrially fabricated ion trap chips designed to investigate radial and axial double-well potentials as building blocks of two-dimensional scalable architectures. The coupling between ions in the double-wells on the chips can be tuned by variation of the radial and/or axial separations.
The ion trap chips are fabricated on dielectric substrates - Fused Silica and Sapphire - at Infineon Technologies [2,3]. We discuss the design and fabrication of the ion traps as well as recent developments.
