"Shall we rant and rave like hysterical monkeys or shall we reason with the Gods?" from The Mind of SAR: Review of objections against my FTL communicator device ( to Mitsu et-al) #1 Nick Herbert's - irreducible incoherence between extraordinary and ordinary alternatives in double refraction. If true it would destroy my effect. So it is a good test of traditional retarded causality. #2 Solovay's: Bob throws a theorem at me and asks if I deny its truth. No I don't deny its truth at all. It is true. I deny its relevance to the actual physics problem. Bob has a very strong flashlight but he is shining it in the wrong room where the key ain't. Given [A,B] = 0, A|a> = a|a>, B|b> = b|b>, and a density matrix D(A,B), the probability distribution for eigenvalues of B is p(b) = Trace[ |b><b|D(A,B)] The joint probability distribution is p(b,a) = Trace[ |b><b| |a><a|D(A,B)], If p(b) = Sum(a)p(b,a), then since Sum(a) |a><a| = Identity(A subspace) there can be no dependence of p(b) on measurements of a. SOlovay's proof will be a more rigorous version of this. First note that in my apparatus Sum(a) is not physical since in the final destiny matrix that matters, only one eigenvalue a occurs in the disentangled state or factorizable destiny matrix D(AB:f) = f(A)g(B) so that p(b) = p(b,a) for that special case. Furthermore there are experimentally controllable parameters some local like phi, m,b and some nonlocal like theta. These parameters determine the very conditions of the experiment. So I am saying that my device takes an initial entangled density matrix D(A,B:i) and maps it to a final disentangled destiny matrix of the form f(B, theta,phi,m,b)g(A) where all the parameters theta, phi,m,b can be controlled and varied from distant A. As I show explicitly the parameters all slip through into B (receiver space) because of the distributive law of algebra when the spin flipper makes |a-> -> |a+> inside the initial entangled pair state - disentangling it. # unitarity violation objection of Steinberg, Caves, and Gallis Be clear two separate experiments: Experiment I is single photon state on transmitter which is only a piece of the pair experiment. The paradox they produce in which conservation of probability is apparently violated is if we look only at the half wave plate as if nothing else is there! That's wrong! That's bad quantum mechanics. I mean it's not standard quantum mechanics. That's where they are wrong. Taking that fragmentary view and given the initial normalized state |-> = [ |E> - |O> ]/sqrt2 -> 0 if only |E> -> |E> and |O> -> |E> The math is impeccable but the physics is wrong. Physics is not math! Physics is Math +! I showed that when you do the problem right according to Feynman and including the mirror and the beam recombiner and the two counters (I,II) you get a very sensible result that conserves probability (eqs. #12& #13) thus for the above dangerous input state |-> that appears to vanish! p(I) = [1 - cos(phi + m -b)]/2[1 - cos(phi + m) cos(b)] p(II) = 1 - p(II) Usually for external reflection with no absorption, the reflection phase shifts m and b of mirror and beam recombiner, respectively, are each equal to pi according to elementary optics books. Therefore, p(I) = [1 - cos(phi)]/2[1 -cos(phi)] = 1/2 even in the limit phi-> 0. My formula can be tested for different b and different m which can be attained! Experiment II is for a different state - a photon pair state and a different apparatus in which the transmitter is only a part of the whole - and we ask what happens not at the transmitter but at the receiver. #3 Josephson and Eberhard - again the wrong criterion for communication. It is simply not true that measurements of commuting operators do not interfere with each other in entangled states according to Schrodinger and de la Torre et-al. But even that is not really relevant to my really original proposal - which I have remote viewed from the future in a precognitive strange loop in time of Godelian self-referential proportions. Indeed my final state is not even entangled! The measurements of the eigenvalues of the commuting operators do not interfere with each other in my final state! The parameters that set "the very conditions of the experiment" (to echo Bohr who smiles down from Superluminal Heaven) do the communicating!
