Commercial photon-counting modules based on actively quenched solid-state avalanche photodiode sensors are used in a wide variety of applications. Manufacturers characterize their detectors by specifying a small set of parameters, such as detection efficiency, dead time, dark counts rate, afterpulsing probability and single-photon arrival-time resolution (jitter). However, they usually do not specify the range of conditions over which these parameters are constant or present a sufficient description of the characterization process.

- The study demonstrates a clear violation of local realism principles by using entangled photon pairs, ensuring all events are spacelike separated.
- The setup includes advanced technology such as rapid random number generators and precise photon detectors, allowing for accurate measurements free from fair-sampling biases.
- The results yield extremely low p values (as small as 5.9×10^{-9}), reinforcing the conclusion that local realism cannot explain the observed phenomena in the experiment.
