论文摘要
我们报告了固态旋转的光学检测到的磁共振（ODMR）的混合信号数据采集系统。该系统是根据辅助高速外围设备辅助的现场编程门阵列（FPGA）芯片设计和实现的。 ODMR实验通常需要高速混合信号数据采集以及一般和特定任务的处理。为此，我们意识到了一个混合信号DAQ系统，该系统可以同时使用精确的硬件同步获得模拟和数字信号。该系统由4个模拟通道（2个输入和2个输出）组成，16个可选的数字通道的工作原理高达125 MHz时钟速率。使用该系统，我们进行了通用ODMR和氮胶菌（NV）中心的高级锁定检测实验，报告的DAQ系统在单个和集合自旋案例中均表现出色。这项工作为NV中心量子控制系统提供了统一的DAQ解决方案，并且可以轻松扩展到其他基于自旋的系统。
We report a mixed-signal data acquisition (DAQ) system for optically detected magnetic resonance (ODMR) of solid-state spins. This system is designed and implemented based on a Field-Programmable-Gate-Array (FPGA) chip assisted with high-speed peripherals. The ODMR experiments often require high-speed mixed-signal data acquisition and processing for general and specific tasks. To this end, we realized a mixed-signal DAQ system which can acquire both analog and digital signals with precise hardware synchronization. The system consist of 4 analog channels (2 inputs and 2 outputs) and 16 optional digital channels works at up to 125 MHz clock rate. With this system, we performed general-purpose ODMR and advanced Lock-in detection experiments of nitrogen-vacancy (NV) centers, and the reported DAQ system shows excellent performance in both single and ensemble spin cases. This work provides a uniform DAQ solution for NV center quantum control system and could be easily extended to other spin-based systems.
