We report on an electronic coincidence detection circuit for quantum photonic applications implemented on a field-programmable gate array (FPGA). which records each the time separation between detection events coming from single-photon detectors. We achieve a coincidence window as narrow as 500 ps with a series of optimizations on a readily-available and affordable FPGA development bo... https://www.diegojavierfares.com/quick-grab-Custom-Made-Esteem-Velour-Seat-Covers-suits-Toyota-Tarago-GLS-Wagon-1985-1989-3-Rows-mega-offer/
