Spatially Resolved Event-Driven 24 × 24 Pixels SPAD Imager With 100% Duty Cycle for Low Optical Power Quantum Entanglement Detection Open
Quantum microscopy requires efficient detectors able to identify temporal correlations among photons. Photon coincidences are usually detected by postprocessing their timestamps measured by means of time-To-digital converters (TDCs), throu…

SPAD Pixel With Sub-NS Dead-Time for High-Count Rate Applications Open
Single-photon avalanche diode (SPAD) exploitation in high-flux applications is often hindered by the trade-off between the SPAD dead-time and afterpulsing probability. In this paper, we present the architecture and the experimental charact…
