Do you still think the experimenters in the real experiment need to know something or anything about the hidden variables? If so, why?

The experimenters need to follow unambiguous instructions. They don't need to "know" about the different theories they are testing. Not once the experimental protocol is written down.

So they don't need to know anything about the hidden variables at all. Correct? If you don't think that is correct, then please explain why they would need to know about the hidden variables.

It seems pretty simple to me. They record the angular momentum directions at particular angles for a and b, then take those results and calculate the correlations per Joy's eq. (16). That is all they have to do. There is nothing else. Their results will either show -a.b, or not or maybe they might discover something inbetween. They don't need to know anything about the simulations if they don't want to. But if you are trying to simulate what Nature might be doing to suit a certain theory, you will have to have those hidden variables in the simulation that the theory says are in Nature.

Ok, that is the last time I am going to explain it. Either you get it or you don't.

It is beyond my understanding why you continue to lie shamelessly about the experimental protocol for my proposed experiment. It has been written down completely unambiguously by me, on the page 4 of my 2008 paper (this one: http://arxiv.org/abs/0806.3078):

You seem to be suffering from severe reading difficulties. Consequently, you have been calculating the four correlations incorrectly, as I have explained to you here:
Joy Christian wrote:

But everything in your world is hardly self-consistent. Among many other things, two of the four correlations you have been calculating do not even reside on the local-realistic correlation surface generated in this simulation in response to your challenge: http://rpubs.com/jjc/19298. I would hardly call that self-consistent.

This contradiction should have made you realize that all the calculations you have been doing are wrong. There is a fundamental inconsistency in your statistical worldview, and my simulation gives you a brilliant opportunity to correct it (albeit at a price of 10,000 Euros).

The correct calculations fully consistent with both my local model as well as my proposed experiment are done in the above simulation. Note the consistency between the four points on the 2D surface (with random a and b) and the four separate correlations calculated in the simulation with fixed a and b. The correct results are:

Code: Select all
 
E(0, 45)  E(0, 135)  E(90, 45)  E(90, 135)
   -0.6993     0.703     -0.699      -0.7276

Now this I call self-consistent.

I have cleaned up some of my other simulations by incorporating what we have learned during the past few weeks.

Here is an example of a cleaned-up simulation of my 3-sphere model: http://rpubs.com/jjc/16567.

The most important conceptual clarification in this simulation is that, what appeared as a "post-selection" of states to the flatlanders, has now been relegated to the "state preparation" of the pre-selected initial states of the system. This was never a problem from the perspective of the 3-sphere, but the flatlanders were having a great deal of difficulty understanding my model because of it. But now the N spin directions, "v", which are actually observed by Alice and Bob, are all pre-selected, thereby removing the last vestige of the Bell-baggage from the simulation.

In summary, N spin directions, "v", as an ensemble of the initial or complete states of the physical system, are pre-selected in the simulation, after the state preparation within S^3, just as we prepare initial states in quantum mechanics and experiments. The correlations are then calculated using the standard formula,

E(a, b) = (1/N) Sum_(k=1)^(k=N) [ sign(+a.v_k) * sign(-b.v_k) ] = -a.b ,

where the measurement directions a and b are randomly selected, respectively, by Alice and Bob. Note that not a single one of Bell's assumptions has been dropped.

Below is a version of Joy's simulation showing that creating the direction files for Alice and Bob that they observe and then reading them back in works in the simulation for when the angles a and b are random. However, if I comment out the write.csv lines and try to read the files back in on a subsequent run, it doesn't work right. The graphic has some distortion in it. Is there some kind of problem with the files syncing with the loop?

Code: Select all
set.seed(9875)

M <- 10^4  ## Sample size. Next, try 10^5, or even 10^6

angles <- seq(from = 0, to = 360, by = 10) * pi/180

y <- sin(r)
u <- rbind(x, y)

## 'u' is a 2xM matrix. The M columns of 'u' represent the x and y
## coordinates of points on a unit circle in the equatorial plane.

p <- 1.21 * (-1 + (2/(sqrt(1 + (3 * s/pi)))))

for (i in 1:K) {
    alpha <- angles[i]
    a <- c(cos(alpha), sin(alpha))
    for (j in 1:K) {
        beta <- angles[j]
        b <- c(cos(beta), sin(beta))
        ua <- colSums(u * a)  ## Inner products of cols of 'u' with 'a'
        ub <- colSums(u * b)  ## Inner products of cols of 'u' with 'b'
        good <- abs(ua) > p & abs(ub) > p  ## Sets the topology to that of S^3
        N <- sum(good)
        q <- x[good]
        w <- y[good]
        e <- cbind(q, w)  ## The spin directions observed by Alice and Bob
        write.csv(e, file = "AliceDirectionse1.txt")
        write.csv(-e, file = "BobDirectionse1.txt")
        ad <- read.csv("AliceDirectionse1.txt")  ## alice directions file
        v <- rbind(ad$q, ad$w)           ## just the x and y coordinates as a 2xN matrix
        rownames(v) <- c("q", "w")
        bd <- read.csv("BobDirectionse1.txt")   # bob directions file
        bv <- rbind(bd$q, bd$w)           # just the x and y coordinates as a 2xN matrix
        rownames(bv) <- c("q", "w")
        va <- colSums(v * a)  ## Inner products of cols of 'v' with 'a'

        corrs[i, j] <- sum(sign(va) * sign(vb))/N
        Ns[i] <- N
    }

par(mar = c(0, 0, 2, 0))

    phi = 30, scale = FALSE, xlab = "alpha", ylab = "beta")

It is good to know that by feeding the spin directions back into the simulation the correlation surface is reproduced exactly. This proves that the spin directions we extracted from the simulation are correct, and Richard is simply doing his calculations incorrectly by fixing the measurement directions a and b "outside the loop."

Interesting. Here Christian admits that his model works by exploiting the conspiracy loophole: the measurement directions need to be known "inside the loop". [I first wrote "inside the loophole"!]

Incidentally, two of our three adjudicators, Hans de Raedt and Gregor Weihs have come out in support of me: the files of directions which Christian submitted did not win the 10 000 Euro challenge - I talk here of the challenge as formulated, not as how it might have been in another parallel universe.

We are still waiting for Andrei Khrennikov, who is probably still recuperating after the excitement of last week, and moreover, I imagine, is a bit computer-challenged, compared to the other two. So no official pronouncement yet.

Now sure, Joy may simulate the hidden variables of his model to simulate the data which his experiment might generate. But unfortunately his simulation has failed to generate data having the properties which he said the data coming out of his experiment would have. Once the experiment is done, some video files are processed. Directions u and v are calculated using image reconstruction software. Then, correlations are computed according to formulas which Christian wrote down on page 4 of his experimental paper. There are no hidden variables involved on the experimental side after the video files have been created. From then on we are in flatland ...
Ok, that is the last time I am going to explain it. Either you get it or you don't.

I can read what is written on page 4 of the experimental paper. I can't make anything different out of it from what I made out of it, and described in the challenge formulated elsewhere on this forum. Christian spent weeks trying to win the challenge as formulated. Now he claims he has won by doing something completely different to what is written in his experimental paper, and moreover something we all here only have known about since a few months ... since I decoded Pearle (1970) and expressed it as a computer simulation.

Seems a bit fishy to me. But everyone can believe just what they like, sure.

Now for sure, Christian can simulate his hidden variables in order to simulate the data which he believes his experiment would generate. But in that experiment, after the video films have been taken of the exploding balls, everything is in flatland. Some image processing software is used to calculate directions of angular momentum u and v of some macroscopic objects. Then a calculation is done following formulas in the paper. Flatland formulas. No more hidden variables.

I am afraid I am unimpressed by Richard Gill’s comments above. In my opinion I have defeated his challenge decisively, by reproducing the entire correlation surface predicted by QM correctly. What is more, I have been able to accomplish this by providing N pre-selected spin directions, as demonstrated in this simulation. This suggests that my proposed experiment will be a spectacular success. It will reproduce the strong correlations exactly as I have predicted in my papers. Contrary to what Richard Gill says, my model has nothing whatsoever to do with the detection loophole or conspiracy theory. It simply points out the correct topology of the physical space, which has been ignored by the Bell community---rather surprisingly---for the past 50 years, as I explain here: http://arxiv.org/abs/1405.2355.

The evidence I have presented so far has been neatly summarized in this simulation of my 3-sphere model: http://rpubs.com/jjc/16567.

The most important conceptual point here is that, what appeared as a "post-selection" of states to the flatlanders like Richard Gill, has now been formulated as a "state preparation" of the pre-selected initial states of the system, originating at the source. This was never a problem from the perspective of the 3-sphere, but the flatlanders were having a great deal of difficulty understanding my model because of it. But now the N spin directions, "v", which are actually observed by Alice and Bob, are all pre-selected at the source (rather than post-selected at the detector), thereby removing the last vestige of the Bell-baggage from the simulation.

In summary, N spin directions, "v", as an ensemble of the initial or complete states of the physical system, are pre-selected at the source, after the state preparation within the 3-sphere, just as we prepare initial states in quantum mechanics and experiments. The correlations are then calculated using the standard formula,

E(a, b) = (1/N) Sum_(k=1)^(k=N) [ sign(+a.v_k) * sign(-b.v_k) ] = -a.b ,

where the measurement directions a and b are randomly selected, respectively, by Alice and Bob. Note that not a single one of Bell's assumptions has been dropped.

On the other hand, Richard Gill's incorrect calculations of the four correlations contradict the evidence presented in this simulation. Note that two of his four correlations do not reside on the correlation surface presented in the simulation. Evidently, he has got his calculations badly mixed up, as I explained previously.

I think we can now say publicly that Christian's bid to win my challenge before June 11 has failed. Gregor Weihs and Hans de Raedt have independently calculated the four correlations from both of Christian's recent submissions and in every case at least one of those correlations deviated more than 0.2 from target (+/- 0.7071).

I suspect that Andrei Khrennikov is not going to respond to the request to adjudicate.

The challenge remains open but the prize now goes down to 5 000.

But of course, if Christian's experiment is ever done, and if it succeeds in reproducing the singlet correlations when the data is processed as in page 4 of the experimental paper and as described in the challenge, then Christian still can win two times 5 000 Euro: once for our original but cancelled bet (because I'm a gentleman), and once for the challenge (if no-one else has won it in the meantime).

However if Christian desires to be vindicated by Nature through experiment, I recommend he revises his experimental paper, explaining to the experimenters how to calculate correlations in S^3 instead of in flatland.

It is quite amusing that you still don't "get it" about the hidden variables. Nature does the S^3 correlations; the experimenters don't have to calculate correlations in S^3. Joy tried to show that better in the latest simulation but you still don't "get it". Your loss.

There is no chairman of the adjudicators. They are self-organizing. The letter I sent to those three gentlemen did not prescribe their internal organization.

But you can bother Andrei if you wish to grasp at straws. As far as I'm concerned, we're finished. However if the three adjudicators together wish to revise the preliminary judgements made by two of the three, I'm willing to hear their arguments. That's all. Do you copy? Over and out.

Christian's, Diether's and Gill's conclusions were foregone conclusions. Gill correctly predicted de Raedt's and Weihs' conclusions. Everything is on record. Everyone else can judge for themselves.
