Highly-Multiplexed Superconducting Detector Readout: Approachable High-Speed FPGA Design

Superconducting devices represent a class of breakthrough technologies enabling detection and manipulation of quantum signals [1] – [3] . Many thousands of interconnected superconducting devices are needed to support quantum error correction for quantum computing and mega-pixel-scale scientific cameras for single-photon-sensing applications [4] – [6] . With each device requiring up to 1 MHz of bandwidth, full readout systems must perform analysis on multi-gigahertz, ultra-wideband signals in real time [7] .
