我们描述了一个低温仪器平台，将商用现场可编程门阵列（FPGA）的操作。在接近4 K的温度下，FPGA的功能可以在低温恒温器内的冷却设备或检测器附近进行信号路由、多路复用和复杂的数字信号处理。在低温环境中的FPGA的性能进行评估，包括时钟速度，错误率和功耗。虽然构造的目的是控制和阅读具有低延迟的量子计算设备，该仪器是通用的，足以在一系列低温应用中广泛使用。
We describe the operation of a cryogenic instrumentation platform incorporating commercially available field-programmable gate arrays (FPGAs). The functionality of the FPGAs at temperatures approaching 4 K enables signal routing, multiplexing, and complex digital signal processing in close proximity to cooled devices or detectors within the cryostat. The performance of the FPGAs in a cryogenic environment is evaluated, including clock speed, error rates, and power consumption. Although constructed for the purpose of controlling and reading out quantum computing devices with low latency, the instrument is generic enough to be of broad use in a range of cryogenic applications.
