Weih's data: what ad hoc explanations do local and non-local models give?

Click For Summary
The discussion centers on Weih's data and the explanations provided by local and non-local models regarding quantum mechanics. Participants highlight the challenges in closing all loopholes in experiments that test local realism, noting that while many have been individually addressed, simultaneous closure remains elusive. The conversation also touches on the implications of coincidence time windows in data analysis, with some arguing that broader windows lead to diminished correlations, indicating potential issues in detection methods. Several analyses of Weih's experiment are referenced, suggesting that the data may not support claims of superluminal signaling or violations of the no-signaling principle. Overall, the discourse emphasizes the complexity of interpreting experimental results in the context of quantum theory and local realism.

I basically did not much more than what you see in the paper on the arXiv. What looks pretty clear is that a local adjustment can be made to the timings that eliminates the timing features at the nanosecond scale that I at first identified in the longdist35 dataset. I didn't look quantitatively at what might be discovered by looking at multiple datasets (which can become a lot of work, so one wants a relatively strong feeling that it might be worthwhile).
I'm not sure whether the Weihs data contains enough information to characterize what parts of the various timing delays are caused by the electro-optical modulator.
You may have missed the concern that was perhaps first raised by De Raedt: a certain amount of unaccounted birefringence could explain the results instead of "non-locality". Regretfully nobody seems to know if this may have been caused by the EOM or not.
BTW: let's get Gregor Weihs' name right. It's not Weih, nor Weih's. Of course I should feel especially sensitive about this, because there's one place in my arXiv paper where I use Wiehs.
Yeah I know, regretfully my spelling error is in the title and I can't change it. :rolleyes:
