项目摘要

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.

超导电路构成了当今最通用的实验平台之一，用于探索量子物理学的基本方面，并构建量子信息处理设备。学术界和工业界的研究活动都是为了建造超导量子计算机。制造和操作超导量子设备非常具有挑战性，需要专门的基础设施，而这仅在德国的极少数地方可用。对超导量子设备进行研究使用实验装置，包括稀释制冷机，以将设备冷却到数十毫开尔文的所需工作温度，以及微波组件和室温电子设备，以生成，过滤，衰减，放大和数字处理控制和测量信号。所要求的系统将包括运行超导量子处理器所需的所有组件，因此将成为所有计划研究活动的关键资源。特别是，低温系统将针对快速周转时间进行优化，并将配备各种不同的测量仪器，以实现时间分辨量子位测量和微波频率谐振器的有效表征。因此，该装置将能够系统地研究材料特性和制造工艺对量子比特相干时间的影响。
