📋 论文概要

该论文提出了一个用于颜色中心量子计算机的低温CMOS控制器芯片，集成了Class-DE驱动器和直流磁场调谐功能。它解决了在几开尔文温度下对氮-空位（NV）中心等量子比特进行精确控制的问题。

💡 主要创新点

• 首次在低温CMOS中集成Class-DE驱动器用于量子比特操控，提高了效率并降低了功耗。
• 集成了直流磁场调谐功能，实现了对量子比特频率的精确调节，支持远程纠缠操作。
• 设计了一种针对颜色中心量子比特的专用控制器架构，优化了低温下的性能与可靠性。

Compared to other qubit technologies typically operating at mK temperatures, the higher operating temperature of NVs enables scalable 3D integration with cryo-CMOS control electronics
