我们报告了我们的系统工程活动，低温CMOS电子作为可扩展量子计算机的构建模块。按照工程的V型模型，该主题是在自上而下和自下而上的方式接近。我们显示的主要结果，从自上而下的研究，使用系统建模和仿真。采用自下而上的方式，在商业65 nm CMOS工艺中设计并实现了原型芯片。该芯片包含一个直流数模转换器（DC-DAC）和一个脉冲DAC作为集成量子比特控制的构建模块。DC-DAC能够将量子比特调谐到其工作点。Pulse-DAC产生具有250 MHz采样频率的脉冲模式，以对量子位执行门操作。
We report on our systems engineering activities concerning cryogenic CMOS electronics as building blocks for scalable quantum computers. Following the V-model of engineering, the topic is approached both in top-down and in bottom-up fashion. We show the main results from the top-down study using system modeling and simulations. In a bottom-up fashion, a prototype chip was designed and implemented in a commercial 65nm CMOS process. The chip contains a DC digital-to-analog-converter (DC-DAC) and a Pulse-DAC as building blocks for an integrated quantum bit control. The DC-DAC is able to tune a qubit into its operating point. The Pulse-DAC generates pulse patterns with 250MHz sampling frequency to perform gate operations on a qubit.
