In the paper I wrote for Statistical Science I was allowed 20 something pages and I already exceeded the original limit repeatedly in one revision after another because the referees kept asking for more stuff. You were not asked to referee the paper. If you had been, you could have asked for a discussion of this point and I would have gladly added it. I'm not going to ask the editors for another two pages, now.

Maybe I will write a supplement and put it on arXiv.

You deny that it is a theorem to begin with, yet you claim to prove it in your paper.

I prove a mathematical theorem in my paper. It's new. I state my theorem and give the proof. If words like "statistics" and "probability" are not in your vocabulary, then you will not even be able to make sense of the statement of the theorem.

No-one even conjectured this theorem before.

Every true mathematical theorem can be considered a tautology. What it has to say about the real world depends on building a bridge between mathematical concepts and empirical things. Even philosophy has this problem: we reason with words, using logic, but the bridge between the words we use, and our actual experiences in the world, might be more tricky than first appears.

In the rest of the papaer I discuss the relation between my new theorem, metaphysics, experimental physics, and simulation models. What is usually called Bell's (1964) theorem is a piece of folklore. Bell was not a physicist and never proved a theorem. Clauser et al., physicists all four of them, were the first to name something "Bell's theorem". If you actually read Bell you will see that Bell completely disagrees with them.

My paper is written for statisticians, for whom this whole topic is completely new. In the abstract I give them a few key words and phrases to hold on to, to motivate them to read the rest of the paper. If I carefully defined every phrase used in the abstract, the abstract would be longer than the paper itself.

I'm on vacation right now so can't really do the detail of Bell's derivation of CHSH but it would be nice if someone could show the extra detail steps for the derivation. And keep in mind that the A and B functions are averages so show them like this, <A(a, lambda)>, etc.

From Michel's thread I gather that Bell's LHV CHSH derivation and Gill's version of CHSH are both "rigged" and nothing can violate them as far as violating a bound of 2. It is also easy to see from that thread that for both QM and quantum experiments the bound is 4 and not 2.

Did we ever resolve the questions at the start of this topic?

Seems to me that Fred Diether doesn't realize that every mathematical theorem is a tautology. It has to be true, by definition. He also doesn't define what exactly he means by "Gill's CHSH" and "Bell's CHSH". Gill derives several auxiliary results and a theorem about a spreadsheet, he then leaves mathematics and discusses experiments and meta-physics. At the end of his paper he turns to computer simulation models and argues that the spreadsheet picture can be a useful tool when exploring the limitations of LHV simulation models, under constraints designed to prevent the simulation from exploiting known loopholes. (Which are of course irrelevant when discussing simulation models of past experiments, because so far every experiment which had been done was badly flawed in one way or another ... something well known for decennia).

He also says "the A and B functions are averages". No: the A and B functions are functions. One can go on to talk about averages which one might denote like <A(a, lambda)>, meaning that A(a, lambda) is averaged over values of lambda in some domain. One had better explain what domain one is talking about and if there is a probability measure involved, what probability measure it is, and what it is supposed to stand for. eg are we averaging over the hypothetical population of all possible values of lambda which might arise in one run of an experiment, weighted according to their relative frequence in this population; or are we talking about an experimental average involving n particular values of lambda realised in n runs of the experiment as n single, independent, draws from that population.

Not making this distinction turns out to be the root cause of endless confusion about Bell, CHSH and all that. Most people participating in increasing the confusion (increasing the noise to signal ratio) did not read Bell's later works where he explicitly paid attention to this distinction, with the aim of getting the signal to noise ratio back on its feet.

The trouble is, theoretical physicsts know nothing about this distinction; experimental physicists know it my instinct but really only know about experiment, not about theory. Hence the bridge is missing in the physics community itself because of inadequate training both of theoreticians and of experimentalists. Neither has a good grounding in probability theory and neither has a good grounding in modern applied statistics. They think they know everything because Gauss already explained that errors always have a normal distribution and that straight lines should be fitted by least squares. It is a very sorry situation, and I have been fighting against it all my career. The younger physicists are beginning to notice that they are missing something. The old ones are fortunately dying out. But before they do so, they are still very influential.

Apparently there are two J. Christians. One at the University of Oxford who, in http://arxiv.org/pdf/0806.3078v2.pdf , wrote "Once the actual directions of the angular momenta for a large ensemble of shells on both sides are fully recorded, the two computers are instructed to randomly choose the reference directions, a for one station and b for the other station—from within their already existing 3D maps of data"

Must have been a different J. Christian.

Christian imposter wrote:Now consider a large ensemble of such balls, identical in every respect except for the relative locations of the two lumps (affixed randomly on the inner surface of each shell). The balls are then placed over a heater—one at a time—at the center of an EPR-Bohm type setup [6], with the common plane of their shells held perpendicular to the horizontal direction of the setup. Although initially at rest, a slight increase in temperature of each ball will eventually eject its two shells towards the observation stations, situated at a chosen distance in the mutually opposite directions. Instead of selecting the directions a and b for observing spin components, however, one or more contact-less rotational motion sensors—capable of determining the precise direction of rotation—are placed near each of the two stations, interfaced with a computer. These sensors will determine the exact direction of the angular momentum j (or −j) for each shell, without disturbing them otherwise, at a designated distance from the center. The interfaced computers can then record this data, in the form of a 3D map of all such directions. Once the actual directions of the angular momenta for a large ensemble of shells on both sides are fully recorded, the two computers are instructed to randomly choose the reference directions, a for one station and b for the other station—from within their already existing 3D maps of data—and then calculate the corresponding dynamical variables sign (j · a) and sign (−j · b). This “delayed choice” of a and b will guarantee that the conditions of parameter independence and outcome independence are strictly respected within the experiment [2]. It will ensure, for example, that the local outcome sign (j · a) remains independent not only of the remote parameter b, but also of the remote outcome sign (−j · b). If in any doubt, the two computers can be located at a sufficiently large distance from each other to ensure local causality while selecting a and b. The correlation function for the bomb fragments can then be calculated using the formula

E(a, b) = 1/N sum_{j =1}^N {sign (j · a)} {sign(−j · b)}, (16)
where N is the number of trials.

On the FQXi blog Richard Gill wrote: “CHSH inequality is a dead issue. Bell's so-called theorem is a dead issue.”

Yes! Finally something I can agree with.

He continues:

“The real question is whether experiment (and simulation) reproduces the theoretical correlation surface which can be derived both by QM and by Christian-LHV:

rho(alpha, beta) = - cos(alpha - beta).”

Yes, again.

He continues:

“Interestingly, the experiment described in the paper http://arxiv.org/abs/0806.3078 (author J. Christian) is very different from all conventional experiments. The paper describes how N runs are performed, resulting in N sets of video film; then, for k = 1, ... , N,two directions u_k and - u_k are computed by analysing the video footage of the k'th run....”

So far so good, but alas he continues:

“... and after that (back home, so to speak), settings alpha and beta are repeatedly chosen at random and A_k(alpha) is calcuated, A_k(alpha) = sign(a . u_k) where a is the direction corresponding to alpha. Similarly B_k(beta) = sign(b . - u_k).”

Wrong!

There is nothing random about alpha and beta. They are settings chosen only once! They are fixed angles or vectors. What is random is the “hidden variable”, u_k in his notation.

Does he now see his error?

Does he now see his error in what he wrote next?

“http://arxiv.org/abs/0806.3078 makes perfectly clear that the same set of N video films of N exploding balls is used to compute two single sets of directions: the directions u_k and - u_k. After that, according to the formulas in the paper, experimental correlations E(alpha, beta) are determined on the basis of the complete set of N runs at a fine by random cloud of points alpha, beta.”

Is he being sneaky again, or is this a genuine oversight on his part?

I agree, CHSH inequality and Bell's theorem are dead issues. Frauds, if you like. The only bound is +4.

The real question is whether experiment (and simulation) reproduces the theoretical correlation surface which can be derived both by QM and by Christian-LHV:

rho(alpha, beta) = - cos(alpha - beta).

A really huge experiment (or really huge simulation experiment) can explore the whole surface, observing the sample correlations E(alpha, beta) = sum_{measurements k with settings alpha, beta} A_k B_k /N(alpha, beta) , where N(alpha, beta) is the number of runs at those two settings. In real experiments, each run k is performed under just one pair of settings. You cannot measure the polarization of one photon in two directions at the same time.

If resources are limited it is wise to restrict attention to a judicious set of settings. The optimal choice turns out to be the four combinations obtained from restricting alpha to the two angles 0 and 90 degrees, and beta to the two angles 45 and 135 degrees. The only reason for this is statistical efficiency. For a fixed number of runs N, if you want maximum discriminatory power between Bell-LHV on the one side, and QM or Christian-LHV on the other side, you should put all your efforts into recovering the correlation surface at cleverly chosen points where the difference between the two theories is largest. Obviously, you want at least two different angles for alpha, and at least two different angles for beta. It turns out that just two of each is best, provided they are these two pairs. This maximizes the power of the experiment. It's a kind of statistical version of Tsirelson's inequality, which as you know can also be proven within Christian's S^3 framework (Van Dam, Gill, Grunwald in IEEE-IT (2005), on arXiv in 2003http://arxiv.org/abs/quant-ph/0307125)

Interestingly, the experiment described in the paper http://arxiv.org/abs/0806.3078 (author J. Christian) is very different from all conventional experiments. The paper describes how N runs are performed, resulting in N sets of video film; then, for k = 1, ... , N,two directions u_k and - u_k are computed by analysing the video footage of the k'th run; and after that (back home, so to speak), settings alpha and beta are repeatedly chosen at random and A_k(alpha) is calcuated, A_k(alpha) = sign(a . u_k) where a is the direction corresponding to alpha. Similarly B_k(beta) = sign(b . - u_k).

The http://arxiv.org/abs/0806.3078 makes perfectly clear that the same set of N video films of N exploding balls is used to compute two single sets of directions: the directions u_k and - u_k. After that, according to the formulas in the paper, experimental correlations E(alpha, beta) are determined on the basis of the complete set of N runs at a fine by random cloud of points alpha, beta.

However Christian appears to have backed off this unorthodox experimental design, thanks to warnings given by M. Fodje. I wonder if he is going to revise http://arxiv.org/abs/0806.3078. Since he's disowned his own experiment, I conclude that he has also withdrawn from our bet.

As I said earlier, it doesn't matter much as CHSH has been successfully exposed as a fraud on this forum. And... since Bell's original inequality is a just a special case of CHSH, then it too is a fraud.

And also... the quantum experiments support Joy's model microscopically (and his model also supports the quantum experiments -- we expect loophole free tests to be possible) so all that is left is for a proper macroscopic test to see if the torsion of space does in fact manifest macroscopically. If not, then we just have to figure out why it manifests only microscopically and not macroscopically. None of this has to do with the fact that Bell's theorem is a completely dead issue.

I did read the whole thread, and I don't understand what you are asking about. Too bad then.

Off topic but related: John Reed is going to make a Mathematica version of the bet resolution script which I wrote. I hope you'll be interested to test it. It needs to be agreed on by Joy's supporters.

I hope it is becoming clear that the whole CHSH inequality business is a bit of a red herring.

We have a theory which says rho(0, 45) = rho(90, 45) = rho(90, 135) = - 0.7, and rho(0, 135) = + 0.7.
We have a theory which says rho(0, 45) = rho(90, 45) = rho(90, 135) = - 0.5, and rho(0, 135) = + 0.5.

"rho" refers to ensemble averages or population means, and are derived on the basis of different mathematical frameworks.

We have experiments in which we can calculate E(0, 45), E(90, 45), E(90, 135) , and E(0, 135) as averages of products of finitely many observed values of binary measurement outcomes, when the experimenters have imposed some different measurement settings on the measurement devices. Usually the four correlations are of course calculated on four different subsets of runs of the experiment, since the measurement devices do not allow to measure according to two settings at the same time. Those four sample averages can in principle take any value between - 1 and + 1, independently on one another, so the only thing one can say for certain is that - E(0, 45) + E(0, 135) - E(90, 45) - E(90, 135) lies between - 4 and + 4.

Joy's proposed experiment is rather remarkable in that it does allow observation of the spin in different directions at the same time. After all, he instructs the experimenter to *measure* u and then to *calculate* A(a) = sign( a . u) and B(b) = sign( b . -u ).

A computer simulation of a LHV model is similar to Joy's experiment in that in the code, a value of lambda is created and a value of A (and of B) is calculated, for particular values of settings a and b. Whether or not one calculates and prints or saves the values of A and B for other values of a and of b, they still do "exist" in a mathematical sense. You may recall how Michel got very angry when I proposed to add some lines to his code doing some different things with the "hidden variables" than he had already written in his code. Because they were "hidden" we were not supposed to look at them. Well, the word "hidden" simply means that in the real world we do not get to see them directly, but just because some physical variable is hidden doesn't mean that we are forbidden to think about it. Einstein, Podolsky and Rosen started this whole thing by thinking about counterfactual outcomes of not performed measurements, and using their thought experiment to infer the existence of hidden variables, hence to logically prove the incompleteness of quantum mechanics - those hidden variables really did exist hence it was the task of the physicist to build models which described them. Which is actually what Joy Christian has done, of course.

Michel is dead on accurate. Violations of inequalities tell us that the analysis is wrong, not that an analytical theory is impossible.

Michel's point is that the only certain bound one can place on an observed value of - E(0, 45) + E(0, 135) - E(90, 45) - E(90, 135), where each "E" is the average of products of measurememt outcomes encoded +/-1 in a different subset of runs, is 4. He is absolutely right. One needs to distinguish between population mean values, and sample averages.

Secondly, performable experiments tend to have ternary outcomes (-1, 0, +1) where one outcome means "no detection". For those experiments one needs generalized Bell inequalities for a 2x2x3 experiment (two parties, two settings per party, three outcomes per party and setting combination). Last year two groups for the first time ever violated generalized Bell inequalities using polarization of photons. The photon polarization is the first quantum system for which each experimental loophole has been closed.

At last the experimenters are using the proper statistical methods advicated for years by Caroline Thompson and championed by people like myself and Jan-Ake Larsson. This is a very gratifying development.

But in the context of Joy's experiment there will be no non-detections and there will in fact only be one set if runs: we'll calculate the four correlations seoarately, but each on the same set of N measured spin directions, exactly according to Joy's instructions in his experimental paper.

The key ingredients are: 1) http://arxiv.org/abs/0806.3078
Joy's experimental paper (and just one page out of that), 2) the agreed terms of the bet, and 3) http://rpubs.com/gill1109/Bet
my R script implementing them.

The paper describes an experiment which results in two computer files each containing N (= 10 000, say) directions. Unit vectors in R^3 encoded e.g. with spherical coordinates theta, phi.

The experimental paper now defines the measurement outcomes as sign(a dot u), sign(b dot v). Actually, we'll have v = - u. Correlations are defined as usual. Joy and my bet is determined by just four of them.

Namely: Alice's angles 0 and 90 degrees; Bob's 45 and 135.

rho(alpha, beta) is +/- 0.5 under LHV, +/- 0.7 under QM

John Reed is working on a Mathematica translation of the script. Michel is working on a Python version. This way, we have complete transparency.

Joy said at the FQXi forum that he already had a simulation experiment, which makes the real experiment superfluous. So he just needs to ask his programmer to adapt the simukation code so as to generate two computer files on N directions in R^3, encoded in spherical coordinates theta, phi. I asked Joy if he could supply the two files within 6 weeks, in time for the Vaxjo conference. I'm willing to raise the stakes to 10 000 Euro but then the terms of the bet are tightened: no files before Vaxjo means I win. Apart from that, everything else remains the same.

(2) Anyways, I suppose it doesn't matter all that much. I was just very curious about Bell's version of the derivation because it is different. But we can easily see from Aspect's derivation that nothing can violate the bound of 2 for CHSH in that version which is the same as yours. The fact that QM predicts a CHSH value of 2.82 for optimal angles is for the version of CHSH where the bound is 4.

(1): you mean from (4.1) to (4.2)? The principle of repeated averaging. Fubini's theorem. E( E(X | Y) ) = E(X). I can explain in more detail, if you like.

(2): like Michel you seem to be unaware of the huge conceptual difference between population mean (ensemble average, expectation value) and sample average (sample mean, experimental mean). Population versus sample.

Statistics! You need statistics! Experimental science needs statistics!
