Hi everyone
While learning about quantum mechanics, I became curious about the real-life experimental data. Wikipedia says that entanglement experiments require coincidence counters, because the majority of the signal received by detectors is noise. It further says, that coincidence counters reduce this noise down to a workable level, but do not fully eliminate it. https://en.wikipedia.org/wiki/Coincidence_counting_(physics)
Could someone with experience in the field educate me about the rough size of the remaining noise?
a) Is this fully negligible, or does it account for a few percent of the real data, or is it more than that?
b) And if the remaining noise is significant: what techniques are used to eliminate it?
c) Is this “normalization” done pre-or post-data acquisition?
Many thanks!
