If no physics experts have genuinely performed such specific physical control run before, I’d be more than happy to share my own experimental results right here in this thread—just want to ensure that it aligns with the PF guidelines and that the moderators and colleagues are comfortable with...

Well, might be, might not be, hopefully not be? But these definitely "be" premature: The Lobotomy Prize (1949), The Parasite-Cancer Blunder (1926), The Fission Oversight (1938) 🤣 Sarcasm aside, if the math is unassailable, the hardware has absolutely nothing to fear from a single, zero-shot...

Professor pointed out the crux of the matter! If we strictly adhere to the standard measurement configuration defined in the CHSH experimental protocol, using the classical paired two-photon states predefined in CH74 to substitute the conventional entangled photon pairs in CHSH experiments, to...

Great inference, fair enough. :biggrin:but our PF truly exists—it has been physically proven by you, myself, @PeterDonis, @Matterwave, @.Scott, @zonde, @FactChecker, and the 943 or 945 lurkers here so far. The empirical existence of a classical control baseline in Bell tests? still nowhere to be...

Plugging p = 0 is just algebraic extrapolation—like inspecting an AI model weights at a theoretical limit rather than a zero-shot test on real hardware. Did they actually load the state and plot the raw counts, or just assume the theory holds? As René Descartes says, we must doubt everything...

Nice to see you dug up the 2006 PRA paper - Fig 2 is really beautiful, but it slightly misses the mark from a data perspective. The "coloured noise" they injected via timing compensation is actually a dephased quantum state, not a true LHV mixture. It tracks how much quantum perturbation the...

With respect, that is not how SPDC physics works. In Type-II SPDC, the output photons naturally emerge in two polarization-orthogonal cones as a product state. Polarization entanglement is only achieved at the specific intersection lines of those cones where spatial mode indistinguishability is...

I have spent considerable time digging through foundational papers and supplementary materials, and have yet to find a single published plot of a physical LHV/product-state run on the exact same apparatus. Since you are a Science Advisor and have access to the literature, perhaps you could...

I really appreciate your comment, especially your historical insight into the fair-sampling loophole. You accurately diagnosed how a classical state can exploit hardware detection profiles to fake a violation. However, invoking the 91% detection efficiency of the 2015 NIST experiment still...

I've been looking closely at the experimental setups for loophole-free CHSH tests, and there's a methodological detail that's bugging me regarding how baseline calibrations rule out hardware artifacts. Mathematically, we know the local hidden variable bound is |S| ≤ 2. But from a purely...
