It's clear that DK's scheme won't work - nor will any scheme that is based on unitary linear orthodox quantum theory using orthogonal base states.
However, concerning Valentini's, Josephson, Weinberg, Stapp & my different & independent from from DK's approaches: while the trace operation to get expectation values of observables on quantum density matrices is invariant under unitary transformations of the base states which preserve orthogonality, that is not true for the transformation from an orthogonal Fock basis to the non-orthogonal Glauber coherent state basis, which is clearly a non-unitary transformation that is OUTSIDE the domain of validity of orthodox quantum theory. I think many Pundits have missed this point?

Thank you, Martin.
I finally get it.
My confusion lay in the attribution of the short calculation below.
I thought this calculation (which leads to rA) was due to Gerry.

Instead it is a calculation done by Gerry but attributed to DK.
It was not a calculation that DK ever carried out but
arose from Gerry taking Gerry's FULL CALCULATION,
applying the Kalamidas approximation
and getting an incorrect result.

The correct result is Zero
on which you and Gerry agree.

So if Kalamidas would have carried out the calculation this way
he would have gotten an incorrect answer.

I hope I have now understood the situation correctly.

But Kalamidas did not carry out the calculation that Gerry displays.
DK did not start out with the FULL CALCULATION and then approximate.

DK starts with an approximation and then calculates.

DK starts with an approximation and carries out a series of steps which all seem to be valid
but whose conclusion is preposterous. Furthermore the approximation (weak coherent states)
is an approximation used in dozens of laboratories by serious quantum opticians without
as far as I am aware leading to preposterous or impossible conclusions.

Therefore it seems to me that the calculation below is another nail in the Kalamidas coffin, BUT

1. No one yet has started with Kalamidas's (approximate) assumptions, and discovered a mistake in his chain of logic.

2. No one yet has started with Kalamidas's (approximate) assumptions, followed a correct chain of logic and shown that FTL signaling does not happen.

Martin Suda came the closest to carrying out problem #2. He started with the Kalamidas (approximation) assumptions and decisively proved that all FTL terms are zero. But Martin's proof contains an unphysical |0>|0> term that mars his triumph.

I am certain that the Kalamidas claim is wrong. The FULL CALCULATION refutations of Ghirardi, Howell and Gerry are pretty substantial coffin nails. But unless I am blind there seems still something missing from a clean and definitive refutation of the Kalamidas claim. See problems #1 and #2 above.

I do not think that Nick is being stubborn or petty in continuing to bring these problems to your attentions. I should think it would be a matter of professional pride to be able to bring this matter to a clean and unambiguous conclusion by refuting Kalamidas on his own terms.

Thank you all for participating in this adventure whatever your opinions.

Thank you for comments!

I would still like to explain my short considerations below a bit more precisely, anyway. I feel there was perhaps something unclear as regards my email (12th June), because you wrote "you were confused".

I only considered the following:

DK disclosed a calculation (see attachment) which is completely wrong because he made a mathematical limit (see first line, where he omitted the term ra^{+}_{a3}) which is absolutely not justifiable here (just as CG mentioned, see below) because both parts are equally important if you make the expectation value properly. If you take both parts you get exactly zero: alpha^{*}(tr^{*}+rt^{*})=0.
So one does not obtain a quantity like (r alpha)^{*}.

That’s all. There is absolutely no discrepancy between me and CG.

Actually, Chris, one can get much more specific than that by explicitly displaying the Correct Approximation Scheme (CAS) and showing term by term than Alice's interference vanishes (to the proper order of approximation).

Absent a correct CAS and its refutation these general claims are little more than handwaving.

Produce a CAS.

What am I missing here?

I wish to say that I accept the general proofs. Kalamidas's scheme
will not work as claimed.
That is the bottom line. So if the general proofs say FTL will fail
for full calculation, then it will certainly fail for approximations.

The "weak coherent state" is a common approximation made in quantum
optics. And dozens of experiments have been correctly described using
this approximation. So it should be a simple matter to show if one
uses Kalamidas's approximation, that FTL terms vanish to the
appropriate level of approximation. If this did not happen we would
not be able to trust the results of approximation schemes not
involving FTL claims.

Gerry's criticism is that Kalamidas's scheme is simply WRONG--that he
has thrown away terms DK regards as small.
But in fact they are large. Therefore the scheme is flawed from the

If Gerry is correct, then it seems appropriate to ask: Is there a
CORRECT WAY of formulating the Kalamidas scheme using the "weak
coherent state" approximation, where it can be explicitly shown that
this correct scheme utterly fails?

It seems to me that there are still some loose ends in this Kalamidas
affair, if not a thorn in the side, at least an unscratched itch.

It seems to me that closure might be obtained. And the Kalamidas
affair properly put to rest if everyone can agree that 1. DK has
improperly treated his approximations; 2. Using the CORRECT
APPROXIMATION SCHEME, the scheme abjectly fails just as the exact
calculation says it must.

Why should it be so difficult to construct a correct description of
the Kalamidas proposal, with CORRECT APPROXIMATIONS, and show that it
fails to work as claimed?

AS seen from the Ghirardi review, there are really not that many
serious FTL proposals in existence. And each one teaches us
something-- mostly about some simple mistakes one should not make when thinking
about quantum systems. Since these proposals are so few, it is really
not a waste of time to consider them in great detail, so we can learn
to avoid the mistakes that sloppy thinking about QM brings about.

When Ghirardi considers the Kalamidas scheme in his review, I would
consider it less than adequate if he did not include the following

Betreff: Re: More on the |0>|0> term

I probably shouldn't jump in on this again, but...

I can assure you that there's no thorn in the side of the quantum
optics community concerning the scheme of Kalamidas. There are only
people doing bad calculations. Despite claims to the contrary, our
paper, as with Ghirardi's, does specifically deal with the Kalamidas
proposal. It is quite clearly the case that EXACT calculations in
the Kalamidas proposal shows that the claimed effect disappears. To
suggest that it's there in the approximate result obtained by series
expansion, and therefore must be a real effect, is simply
preposterous. All it means is that the approximation is wrong; in
this case being due to the dropping important terms.

The whole business about the |00> and whatever (the beam splitter
transformations and all that) is not the issue. I'm astonished at
how the debate on this continues. The real problem, and I cannot
emphasize it enough, is this: Kalamidas cannot do quantum optical
calculations, even simple ones and therefore nothing he does should
be taken seriously. As I've said before, his calculation of our Eq.
(9), which I have attached here, is embarrassingly wrong. It's
obvious from the expression of the expectation value in the upper
left that there has to be two terms in the result both containing
the product of r and t. But Kalamidas throws away one of the terms
which is of the same order of magnitude as the one he retains. Or
maybe he thinks that term is zero via the quantum mechanical
calculation of its expectation value, which it most certainly is
not.  His limits have been taken inconsistently.  So, he not only
does not know how to do the quantum mechanical calculations, he
doesn't even know how or when the limits should be taken. There's
absolutely no point in debating the meaning of the results incorrect
calculations. Of course, by incorrectly doing these things he gets
the result he wants, and then thinks it's the duty of those of us
who can do these calculations to spend time showing him why his
calculations are wrong, which he then dismisses anyway.
My point in again bringing this specific calculation of his is not
to say anything about his proposal per se, but to demonstrate the
abject incompetence of Kalamidas in trying to do even the most
elementary calculations.  And if anyone still wonders why I'm angry
about the whole affair, well, what should I feel if some guy unable
to do simple calculations tries to tell established quantum optics
researchers, like me and Mark Hillery, that our paper showing where
he's wrong dismisses ours as being "irrelevant?" He doesn't even
seem to know that what he said was an insult.

And finally, the continued claim that the specific proposal of
Kalamidas has not been addressed must simply stop. It has been
repeatedly. I suspect this claim is being made because people don't
like the results of the correct calculations. That's not the problem
of those of us can carry through quantum optical calculations.

 Think of it this way: Suppose you just have an EP source that
creates pairs, with one photon going left and the other right.
Imagine that on the right there is a highly trasnparent BS with
|r|^2=0.001. That means that only one out of every thousand right
photons from the EP are reflected, and 999 are transmitted. So,
this means that for every 1000 counts ON THE LEFT, there will be
999 counts tranmitted on the right. Now introduce, at the other
input of that same BS, a CS so that it has a tiny reflected
portion of amplitude |ralpha>. Allegedly then, there will arise
cases where no photon is found in the transmitted channel with
probability equal to |ralpha|^2. Since alpha is arbitrary, we can
choose |
ralpha|=0.1. This means that the probabilty of getting no

the transmitted channel will be |ralpha|^2=0.01.....Which now
means that, for every 1000 EP pairs created, we will get 1000
counts on the left, but only 900 counts in the transmitted channel

would be
999 counts on the right for that same 1000 counts on the left.

OK, here is a simple case - not same as Kalamidas mind you - that seems to be outside the rules of orthodox quantum theory.

Alice the receiver has an ordinary orthodox quantum bit with base states |0> & |1> for a given orientation of her apparatus which never changes in the experiment. Bob the sender has two distinguishable non-orthogonal Glauber coherent eigenstates |z> and |w> of the non-Hermitian observable boson destruction operator a, where z and w are complex numbers. Right at this point we have violated one of the axioms of orthodox quantum theory in a factual way since Glauber states are facts.

Suppose we have the entangled state

|A,B> = (1/2)^1/2[|0>|z> + |1>|w>]

then using the orthodox Born probability rule in density matrix formulation gives

p(0) = p(1) = (1/2)[1 + |<z|w>|^2]

p(0) + p(1) = 1 +  |<z|w>|^2 > 1

the entanglement signal at Alice's receiver is  |<z|w>|^2 violating conservation of Born's rule for probability - because the observable is not hermitian and actually a closer examination shows a non-unitary time evolution. This is a larger theory that reduces to orthodox quantum theory in the appropriate limit.



Now, we can squirm out of this by a-priori ad-hoc forcing of the non-universal normalization

|A,B>' =  [1 +  |<z|w>|^2]^-1/2|A,B>


p'(0) = p'(1) = 1/2 with no signaling Note, that Bob does not need to use that normalization at all because of Alice's <0|1> = 0.

That's why I use "non-universal" above.

However, it's not clear the Nature works this way without more testing.

As regards the approximation done in the calculation of DK, I would like to point out again - and I sent a pdf called Interf_BS_50_50_Suda.pdf two days ago -  that because of such an approach the normalization of the output wave function behind the 50/50 BS has been changed to (1+2|alpha|^2+|alpha|^4), see Eq.(7), instead of being exactly 1. The probabilities for the potential "interference part" (see Eq.(6)) are (|p_10|^2+|p_01|^2)/4=2|alpha|^2 and the other parts give all together  2(|q_10|^2+|q_01|^2)/4=1+|alpha|^4. One keeps therefore precisely the modified normalization of Eq.(7). One can clearly see that the "interference part" and the other parts are outcomes from an incorrect normalization.

In both Ghirardi's and Gerry's papers, they emphasize these general considerations and decline to engage in the specifics of Kalamidas's calculations. Whether one wishes to engage the specifics or not is a matter of taste. But Kalamidas is asking us to engage in specifics. As he puts it: Since you know that I am wrong, it should be "easy pickins" to
point out exactly where I am mistaken.

Gerry comes closest to meeting Kalamidas's challenge to move out of the safety of generalities and deal with specifics.

In the conclusion of Gerry's paper he states "Clearly, if the exact calculation shows no interference, but the approximate calculation does, there is something wrong with the approximate calculation. Looking at Eq 6, one notes that while some terms to order rA have been kept in going from 6a to 6c, the terms labeled "vanishing" in Eq 6b are also of this order and have been discarded. Thus the approximate calculation in {1} is inconsistent and wrong."

Gerry engages in specifics. He is meeting Kalamidas on his own terms. But he neglects to specify exactly which terms of order rA Kalamidas has mistakenly labeled as "vanishing". When Gerry displays these wrongly-neglected terms (perhaps in an informal note), he would have definitively "slain the beast in his own lair" and we can all get on with the non-Kalamidas aspects of our lives.

JS: Agreed, thanks Nick :-)


PS: There is still the fascinating Martin Suda Paradox which was discovered in the context of the Kalamidas refutation, but that is a separate issue altogether.

yes I agree with this
any attempt at signaling within axioms of orthodox quantum theory will fail e.g. Adrian Kent's papers
however, antony valentini, myself and others (Stapp, Weinberg, Josephson) have all independently proposed several extensions giving a more general non-orthodox post quantum theory containing orthodox quantum theory as a limiting case. In particular, the non-hermitian boson destruction operator is a macroscopic observable with Glauber coherent eigenstates that are non-orthogonal distinguishable violating orthodox quantum theory. Furthermore, they obey a non-unitary dynamics given by the c-number landau-ginzburg equation for spontaneous broken symmetry ground/vacuum state emergent local order parameters. These order parameters entangle with others and also with orthodox qubits, so we have a new larger theory here analogous to general relativity in relation to special relativity.

Furthermore, there is no violation with the group structure of relativity because  intervals are frame invariant and what matters is the interval between actual irreversible detections. What is violated is the retarded casuality axiom appended to relativity that is adhoc like Euclid's fifth axiom. Again the analogy to non-Euclidean geometry is appropriate.
