|Bob> = |w>B|+>B + |w'>B|->B trapped ion
Entanglement swap the internal trapped ion discrete qubit states, leaving the Glauber coherent states fixed.
|Alice>, |Bob> ----> |Alice'>, |Bob'>
|Alice'> = |z>A|+>B + |z'>A|->B
|Bob'> = |w>B|1>A + |w'>B|0>A

There is a very intuitive though not simple way to understand the space-time crystal.
1) spontaneous broken symmetry in complex many particle systems. These are quantum phase transitions like when our observable universe is created in the moment of inflation out of the pre-existing unstable false vacuum in which all particles have zero rest mass because the Higgs field had not yet formed. The appearance of the Higgs field is the effect spontaneous broken symmetry in which the post-inflation quantum vacuum of our expanding universe. The quantum vacuum has less symmetry than do the field equations for some of the matter fields.
2) Quantum field theory shows that matter exists in two very different forms - real and virtual. Matter in virtual form lives inside the quantum vacuum briefly popping into and out of existence. We see this indirectly in small shifts of spectral lines of atoms (Lamb shift) and in the Casimir zero point force between two neutral plates. Virtual particles do not transport energy outside the "near field" and they cannot directly cause a counter to click only real particles can do that. The LHC just showed us a real Higgs boson kicked out of the vacuum by the tremendous focused energy of the machine. It's like chipping a small piece of ice out of a huge glacier that is the VIRTUAL Higgs-Goldstone spontaneous broken symmetry field inside the vacuum. There are two kinds of spontaneous broken symmetry particles. The Goldstone particle has zero rest mass like the photon particle of light. The Higgs particle has a finite rest mass now seen at about 125 Gev in the LHC. There may be several Higgs and Goldstone particles. The Higgs and Goldstone particles come in conjugate pairs like the amplitude and phase of a coherent laser beam wave. In fact the Higgs-Goldstone vacuum field is mathematically somewhat similar to a laser beam field with some important differences of course. The mathematics of these general "coherent states" was worked out in the early 1960's by Nobel Laureate Harvard physics professor Roy Glauber. Basically we have a large number of particles all in the same single-particle quantum state although that actual number is uncertain and in the simplest case has a Poisson distribution.This happens not only in lasers but in superconductors and as we see below even in Frank Wilczek's space-time crystal. The difference is that the Higgs vacuum field that itself gives rest masses to the leptons and quarks is made up of huge numbers of VIRTUAL Higgs-Goldstone conjugate particle pairs that form a set of complex numbers z in the polar representation for those of you who know some high school math where z = Rexp(itheta). R is the amplitude and theta is the phase. The massive Higgs particle in real form are quantized vibrations in the amplitude R like you AM radio. The massless Goldstone particles in real form are quantized vibrations in the phase theta of the coherent vacuum field like your FM radio roughly.
3) A space crystal is a periodic lattice of atoms that forms in a quantum phase transition in which the continuous translational symmetry of the higher temperature gas or liquid is spontaneously broken down to a much smaller discrete crystal group. The phonon is a massless Goldstone particle. The analogous Higgs particle would be a phonon sound wave with an energy gap at infinite wavelength. However, a single phonon is a collective normal mode of all the real atoms that form the crystal lattice. Now real phonons that propagate sound energy have a frequency that is the speed of sound divided by the wavelength. However, virtual phonons do not obey that relationship at all. Indeed, the crystal lattice itself is a Glauber coherent state of a huge uncertain number of VIRTUAL PHONONS all in the same single-phonon quantum state. These particular virtual phonons have zero frequency with finite wavelengths along the three directions of space that are determined by the particular discrete space-crystal group that is not spontaneously broken. A very similar thing happens for electromagnetic photons in the ordinary electrostatic Coulomb field e/r potential energy per unit test charge q in the rest frame of a point charge e where r is the distance between e and q. The longitudinal electrostatic field is a coherent Glauber state of a huge uncertain number of virtual photons of zero frequency with a whole continuum of wavelengths along the three dimensions of space.
4) We now have a unified conceptual framework. The space-time crystal is simply a Glauber coherent state of again virtual phonons but this time with a finite frequency and the same set of discrete wavelengths as in the space-crystal.

LONDON APRIL 10, 2012 ENTANGLEMENT SIGNALS?
I suppose this may be considered a rear-guard action leaving no stone unturned in the general belief in no-entanglement signaling in the sense of papers of Adrian Kent even though papers by Antony Valentini suggest otherwise. Of course, orthodox micro-quantum theory does not allow stand-alone entanglement signals no one denies that. The issue is whether orthodox quantum theory is the final complete theory of reality. Einstein did not think so. General quantum theory would be to orthodox quantum theory the way general relativity is to special relativity. Experiments by Libet, Radin, Bierman, Bem and others seem to provide evidence for entanglement signaling in mental activity. Roger Penrose discusses early experiments by Libet in his books. The discovery of dark energy accelerating the universe’s expansion is evidence for retro-causality when combined with the t’Hooft-Susskind hologram conjecture. Yakir Aharonov’s post-selected destiny state vector weak measurement quantum theory though not having stand-alone entanglement signaling is easily extended to include it. John Cramer has proposed an experiment to test for Wheeler-Feynman “transactional" back from the future influences. Henry Stapp. Jorge Berger has shown how Glauber macro-quantum coherent state Landau-Ginzburg emergent Higgs-Goldstone order parameters have nonlinear non-unitary local dynamics violating the linear unitarity of micro-quantum theory. The Vitiello-Freeman brain dynamics is an example of what Berger is talking about. Indeed, P.W. Anderson’s emergent “More is different” must be taken more seriously. Einstein’s gravity as curvature itself in the tetrad/spin-connection Cartan formalism seems to be a spontaneous broken emergent c-number Higgs-Goldstone post-inflation “vacuum superconductor” field with residual local de-Sitter conformal gauge group symmetry.

This is not a pre-post selected correlation but a local signal without a classical signal key to unlock it like in quantum teleportation.
The 2003 Rev Mod Phys paper by Leibfried on trapped ions has the entanglement coherent phase signal I calculated in general in my three talks 10-1-11 DARPA-NASA Star Ship Orlando Hilton, 11-1-11 SLAC APS Stanford University, & 2-27-12 Boston APS. However, both the sender and receiver are Siamese Twins, i.e. the phase coherent center of mass motion of the trapped ion as the sender and an internal qubit of the same ion as the receiver. Nevertheless, orthodox quantum theory says the signal output of the qubit should be uncontrollable random noise 1/2 in proper units. In fact there is a non-random signal in the real data that obeys my general equation! So it's a first step. We may need to use quantum teleportation to get the sender and receiver spatially separated - another problem. Also, even if the sender and receiver are on the same ion can the sender act back from the future on the receiver as in the brain presponse reported by several independent people Libet -> Radin -> Bierman -> Bem.
Therefore, it still looks to me that the Born probability rule breaks down completely for entangled Glauber states as I originally said.
So I still expect that the results below are actual LOCAL data not correlation computations. However, Ruth is correct we need to check with the people who did the experiment.
