一种基于FPGA的深低温测量平台
An FPGA-based Instrumentation Platform for use at Deep Cryogenic Temperatures
摘要：
我们描述了一个低温仪器平台，将商业上可用的现场可编程门阵列（FPGA）配置为运行远超过其指定的温度范围。该仪器能够在接近4开尔文的温度下进行信号路由、多路复用和复杂的数字信号处理，并靠近低温恒温器内的冷却设备或检测器。系统的低温性能进行了评估，包括时钟速度，错误率和功耗。虽然构造的目的是控制和读出具有低延迟的量子计算设备，但该仪器足够通用，可以在一系列低温应用中广泛使用。
英文摘要：
We describe a cryogenic instrumentation platform incorporating commercially-available field-programmable gate arrays (FPGAs) configured to operate well beyond their specified temperature range. The instrument enables signal routing, multiplexing, and complex digital signal processing at temperatures approaching 4 kelvin and in close proximity to cooled devices or detectors within the cryostat. The cryogenic performance of the system 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.
