Isolating the classical and quantum coherence of a multiphoton system. Chenglong You et al. 2024
Once again the theorists forget that their coincidence counters, called correlation counters in this study, are the magic card trick mechanisms creating the imaginary quantum effects which the researchers claim are being observed. In reality the observed data has nothing to do with spooky magic action at a distance.
No wonder they supposedly found that classical light sources seem to behave as if they were being subjected to quantum effects. When all that really happens in these ridiculous experiments is that light from different detectors with different polarised states, arrives at the coincidence counter. Where the data is collected , collated and then later matched up as “coincidences” by researchers to make their imaginary quantum effects appear. Where in truth there are none. It can all be explained classically with polarisation.
It’s a simple card trick used by Quantum researchers ever since the early days of the fakery of quantum eraser experiments as described at the link below.
Basically what all these Quantum experiments do is divide the original light beam into three paths to three detectors. One is the original beam going to a master detector D1 measuring all states of vertical V and horizontal H polarisations. etc. V,H,V,H,V,....etc
Then two more paths with either only V or H beams go to two other detectors D2 and D3. So for instance, D2 gets only the Vertical polarised portion of the cycle and the other detector D3 only receives the Horizontal polarised portion of the cycle. Notice now that a correlation counter will match detections from D2 to D1 but at the same point in time...NO DETECTIONS from D3 to D1 will be recorded. Because the original emitted beams polarisation alternates and therefore peaks at different times between the vertical and horizontal polarised states each cycle.
This isn’t quantum magic. This is creative accounting making classical polarisation look like quantum magic.
