Scaling TIQC to thousands of ions requires microfabricated traps produced in highly reliable facilities. Industrial fabrication provides precise process control as well as in-line measurements tools that ensure high reliability and reproducibility.
Various ion trap designs have been produced at Infineon Technologies cleanroom facilities, including 2D ion trap arrays and 3D traps assembled at wafer level. In this talk I will report on our current work towards large-scale ion traps, including fabrication on dielectric substrates (fused silica, sapphire), through-glass-vias, use of Kelvin probe force microscopy for DC surface potential measurements, integration of fs-laser-written optical waveguides, and development of electronic devices that can operate at 4 K.
