Both sources and detectors are probabilistic. I'd like to see how this argument fares using energy resolving detectors like TESs. I do not expect the probability of a detection event in one spot to be affected instantly by a detection event somewhere else. The collapse of the wave function is an attempt to apply statistical reasoning to a single event. Jeroen Belleman
