We must distinguish several variations and options in trying to achieve
quantum connection communication in the context of the insufficiency of the
NO-GO FTL proof based upon unitarity of time evolution between measurments.

1. Transmitter has two detectors.

The difference in the two receiver counter firing rates is then
proportional to

p(V') - p(H') = sin (2theta)cos(phi)cosb

theta is the nonlocal misalignment between the two calcite rhombs at the
two, generally non-simultaneous times (even in rest frame) of local
interaction of each photon in the pair with its calcite. phi is phase shift
of transmitter photon caused by phase-plate in the extraordinary path of
transmitter interferometer before the recombiner. b is the relative phase
shift between reflected and transmitted outputs of the transmitter beam
recombiner (for the extraordinary and ordinary rays from transmitter
calcite). The ordinary ray has be rotated to an extraordinary polarization
by a 90 degree rotation from a half-wave plate before the recombiner.

Conservation of energy at the passive transmitter recombiner demands that b
= pi/2.  Therefore the quantum connection receiver signal is zero on
average, though not in the mean square fluctuation!

It is not clear what would happen if we use an active (i.e. laser
amplifier) transmitter beam splitter which might shift b away from pi/2
giving a nonvanishing mean signal at the receiver.

This model has no missing factor of 2. All local probabilities add to 1
exactly on each side.


2. Transmitter has only one detector. This has missing factor of 2. Again
mean signal appears to vanish because of sum over different diffraction-
limited spots on extended photo-sensitive surface of transmitter detector
which entail summing over all phase differences from the two output ports
of the recombiner.  However, this is a macroscopic geometric effect of path
differences. It is a classical contingent factor not part of the
microscopic NO-GO proofs base on unitary transformations.  Similalry for
cosb in case 1.  It is not clear is a clever phase-compensation plate
(perhaps an active inverted atomic population in the material as well)
cannot extract a useful quantum connection signal in the mean.  Again the
signal can be extracted in the local receiver fluctuations - the signal is
literally in the noise which is modulated by quantum action at a distance.

Remember the Unruh work showing that Minkowski vacuum is like a BCS pair
correlated state of virtual Rindler photons corresponding to detectors in
uniform accelerated motion detecting blackbody radiation in vacuum similar
to Hawking radiation.  This suggests a curious connection to be explored
later.  In accord with Brian Josephson's suggestion in an OMNI magazine
interview - our mental machinery at the molecular level that we experience
as ideas, feelings, perceptions may be connected with Casimir zero point
forces in chemical cage "cavities". That is, we may be sensitive to
modulations in the zero-point fluctuations via information flows between
Rindler photons in pair correlated states.  We also have Penrose's idea
that decoherence of quantum pure states is a low energy graviton effect in
which quantum gravity shows itself way above the Planck scale in everyday
life.
