Here is an important historical factoid:
The above experiment was published on the 29th of October 2015, just 14 days after the theory behind it was published here: http://arxiv.org/pdf/1103.1879v2.pdf.

So the bogus propaganda by the topologically naïve Bell believers continues: http://www.nature.com/nature/journal/va ... 15631.html
As some of us already know, the title of this article is an outright lie. Unfortunately there are plenty of people out there who desperately want to believe this lie.

The bogus propaganda by the "quantum" mysterians continue shamelessly: http://arxiv.org/abs/1511.03190 ,
even though this type of experiments with photons have long been explained by my 3-sphere model purely local-realistically: http://arxiv.org/abs/1106.0748.
Eventually the fraud-busters will catchup with the "quantum" mysterians. The following derivation is just the beginning: viewtopic.php?f=6&t=207&p=5754#p5732.
Nota bene: There are NO LOOPHOLES exploited in this derivation: https://www.academia.edu/17783877/Dispr ... 501.03393_.

I just learned that the Delft team, which performed the so-called “loophole free” experiment, had a 50 million dollar investment form the INTEL Corporation, a company with a huge vested interest in building a “quantum computer.”
I don’t have an independent confirmation of this gossip. I just learned about it from a comment by Teresa Mendes on the FQXi blog. But if true, then no wonder why the Delft team was so keen on proclaiming the “death of local realism”, just as Clauser et al. did in the 70’s, and Aspect et al. did in the 80’s.
Buried under money, power, politics, and vested interests, the "truth" is difficult to find in these experiments.

I am sorry that you prefer to ignore the evidence I have presented and side with a manifestly erroneous argument by Belll and his followers. I doubt that you will change your mind, but let me show you, in just a few steps, how absurd Bell's argument is (independently of the explicit and irrefutable evidence I have presented above in support of my manifestly local model for EPRB).
Quantum mechanics is a theory of physics. It makes predictions for possible ***physical*** experiments. It makes no prediction whatsoever for the Bell-CHSH quantity
E(a, b) + E(a, b’) + E(a’, b) – E(a’, b’),
because no experiment can ever be performed (even by "God") which can measure that quantity. On the other hand, quantum mechanics does make definite predictions for the quantities (or expectation values) E(a, b), E(a, b’), E(a’, b), and E(a’, b’) individually. Therefore one has to be extraordinarily naïve to think that the Bell-CHSH inequality
E(a, b) + E(a, b’) + E(a’, b) – E(a’, b’) < 2
has any relevance whatsoever for physics.
One can see Bell’s argument as an elementary logical fallacy, relentlessly committed by the Bell supporters with a straight face. What is possible (and actually observed in any Bell-type experiment) is
E(a, b) OR E(a, b’) OR E(a’, b) OR E(a’, b’),
since a, b, a’, and b’ are mutually exclusive observation directions (evidently, one can either be in New York or in LA, but not in both places at the same time). The corresponding inequality then is
E(a, b) + E(a, b’) + E(a’, b) – E(a’, b’) < 4
which has never been violated in any experiment.
But Bell and his supporters superstitiously replace the above logical string with
E(a, b) AND E(a, b’) AND E(a’, b) AND E(a’, b’),
which is a quantity that can never be observed in any experiment, because, once again, a, b, a’, and b’ are mutually exclusive observation directions. All one needs is an elementary lesson in logic to recognize the fallacy in replacing OR with AND --- i.e., replacing physics with nonsense.
What is flabbergasting is that the Bell supporters have been able to mislead the entire physics community for over 50 years with such an obvious sleight of hand. No statistical trickery can mask this Uri Geller-type sleight of hand in logic.

I suggest that the Bell-CHSH quantity, a straight-forward physically-significant expression, is predicted by QM and that it is readily derived from a Bell-test in which Alice is free to select detector settings a or a' while Bob is free to select settings b or b'. Then (as is now well-known), for some settings, the Bell-CHSH limit of 2 will be exceeded.

Thanks, Gordon.
You are talking about a "theoretical" prediction of quantum mechanics [ that of Tsirel'son's bound of 2\/2 ] for counter-factually possible but mutually incompatible observation directions. That prediction is indeed straightforward as you say. I myself have derived it many times within my own local-realistic framework --- see, for example, the extensive discussion we had at this thread of the forum and links to several of my papers therein. See also: viewtopic.php?f=6&t=196&start=50#p5458.
On the other hand, my sentence you quote above is obviously true, because a, b, a', and b' are mutually exclusive observation directions corresponding to physically incompatible four experiments. What I am saying there is that Bell-CHSH quantity cannot be observed directly in any experiment, for example in a given single run.
We have of course gone through all of these issues to death in this forum. See for example this quite succinct discussion by Michel: viewtopic.php?f=6&t=199#p5528.

Why is this so hard for otherwise intelligent people to understand?
