Trapped ion quantum computing platforms in cryogenic vacuum have the advantage of rapidly achieving ultra-high vacuum. This allows long ion storage times even in the relatively shallow trapping potential of surface-electrode Paul traps. In addition, it offers more flexibility in exchanging trap chips, making it feasible to study multiple generations of traps with different structure and experimental specifications. Here, I will discuss the progress towards building and operating a cryogenic (4 K) quantum demonstrator that includes low-noise cryogenic electronics to precisely control trapping potentials and enable shuttling of ions (BMBF-funded project ATIQ). En route towards scalable trapped ion quantum processors, multiple generations of microfabricated surface-electrode traps with integrated magnets and cryogenic control electronics will be investigated in this platform.
