Superconducting circuits constitute one of today's most versatile experimental platforms to explore fundamental aspects of quantum physics and to build devices for quantum information processing. Intense research activies both in academia and industry are geared towards building superconducting quantum computers. Fabricating and operating superconducting quantum devices is very challenging and requires dedicated infrastructure, which is only available at very few places in Germany. Performing research on superconducting quantum devices uses experimental setups which consist of a dilution refrigerator to cool down the devices to the required operating temperatures at tens of Millikelvin, as well as microwave components and room-temperature electronics to generate, filter, attenuate, amplify, and digitally process the control and measurement signals. The requested system will comprise all the components, which are required to operate superconducting quantum processors and will thus be a key resource for all the planned research activities. In particular, the cryogenic system will be optimized for a rapid turn-around time and will be equipped with a variety of different measurement instruments to enable both time-resolved qubit measurements and the efficient characterization of microwave-frequency resonators. As such, the setup will enable systematic studies of the influence of material properties and fabrication processes on qubit coherence times.
