The standard argument against faster-than-light communication in quantum
field theory (e.g., LBL-24984 P.H. Eberhard & R.R. Ross) is mathematically
incorrect (Found. Phys. Letters, 4, 49-59 1991 A.C. de la Torre et-al).

Eberhard's error is the assumption that the vanishing of the expectation
value of the space-like separated local observables is sufficient to
exclude Heisenberg incompatibility outside "each other's light cone".
Eberhard's condition, while necessary for such a conclusion, is not
sufficient as shown in 1930 by Schrodinger (Berliner Berichte 296).
Eberhard, and the standard textbooks and published papers on dispersion
relations, have not recognized the contribution of the entanglement of
the multiparticle states to the Heisenberg incompatibility. In particular,
de la Torre et-al show that Heisenberg incompatibility, hence communication,
exists between the commuting spin operators of spinor particles in the
singlet state even when they are outside each other's light cone.

This means that the retarded causality postulate is wrong. Effects can
happen before their causes at the quantum level. This fact does not
violate the established tests of special relativity (i.e. time dilation and
mass-energy equivalence). Evidence for violation of dispersion relations
in gamma proton scattering has been published in 1987 Physical Rev. A
by Chas Bennett of Lawrence Livermore.

In this series of lectures I show how to construct a practical faster-
than-light (FTL) and backwards-in-time (BIT) "quantum delayed choice"
(i.e., John Wheeler's term) photon pair communication device using a
simple modification of John Clauser's experiment.

The transmitter is a calcite rhomb interferometer. The V output is
passed through a variable phase plate which encodes the message by
phase modulation. The output from the phase plate is sent to a non-
absorbing fully reflecting mirror and then to a half-silvered mirror
where it is recombined with the other path. The other H rhomb output
is passed through a half wave plate changing H to V before reaching
the the half-silverd non absorbing beam recombiner. The two outputs
of the beam recombiner are sent to separate photon counters of the
transmitter. On the opposite side of the pair source we have the receiver
which is simply another calcite rhomb whose two outputs go to separate
counters.

The Feynman rules of standard quantum mechanics (consistent with the
1930 Schrodinger theorem re-presented by de la Torre et-al) of adding
ampltudes before squaring for indistinguishable histories and squaring
before adding for distinguishable histories imply the following prediction
that can be immediately tested in a real experiment.
