A 32×32-pixel time-resolved single-photon image sensor with 44.64μm pitch and 19.48% fill-factor with on-chip row/frame skipping features reaching 800kHz observation rate for quantum physics applications

Entangled photons, beyond the classical physics understanding, show quantum correlations in some of their degrees of freedom. They find application in quantum computing, quantum key distribution, and super-resolution (i.e., beyond the diffraction limit) microscopy, but they are undistinguishable using conventional image sensors.
