Trapped ion quantum computing platforms in cryogenic vacuum have the advantage of providing extreme high vacuum (XHV) allowing for long ion storage times, even in the relatively shallow trapping potential of surface-electrode Paul traps. Furthermore, anomalous heating of trapped ions is strongly suppressed. Here, we will discuss the progress towards building and operating a cryogenic quantum demonstrator that includes low-noise cryogenic electronics to precisely control trapping potentials and enable shuttling of ions. En route towards scalable trapped ion quantum processors, multiple generations of microfabricated surface-electrode traps with integrated magnets and cryogenic control electronics are investigated in this platform.
