Dear alden. If you send light through an absorbing polarizer, the light
that comes out is polarized in one direction - so it's not impossible.

In my device the transmitter (which catches only one of the two connected
photons from the atom. The other twin photon moves off in opposite
direction to the receiver.) consists of several stages. The first stage is
a standard specially cut calcite crystal that splits the incoming
unpolarized light into two spatially separated beams. One beam is polarized
in a direction determined by the orientation of the calcite. The other beam
is polarized perpendicular to that direction. So far, all standard double
refraction crystal optics.

In the second stage, one of the polarized beams passes through a phase
plate which is simply a glass plate shaped like a wedge. By moving the
plate up or down the beam goes through different thicknesses of glass which
introduces a variable "phase retardation". This is the phase modulator for
encoding information on the nonlocal quantum connection communication
channel that exists in the Wheeler "pre-geometry" beyond space-time.

Still in the second stage, the other beam passes a standard half-wave plate
which has the property that it rotates the plane of polarization of that
beam by 90 degrees. Therefore, both separated beams have the same direction
of polarization when they enter the third stage.

The third stage is a system of mirrors directing the beams into a half
silvered "recombiner" plate that recombines the two beams and mixes them.
The recombiner has two mixed beams (called "interferograms" for ordinary
uncorrelated light) that exit the plate in perpendicular directions.

The refutation of my original design based on "unitarity" is that the
relative phase shift between transmitted and reflected waves out of the
recombiner must be 90 degrees in order to conserve energy - the only
alternative would be drawing energy from the vacuum which seems far
fetched.

In the original design, in the fourth stage, the two outputs from the
recombiner went to separate counters. The standard quantum equations (based
on the Feynman rules for how to add quantum amplitudes - not his "diagram"
rules) then predicts the equal statistically averaged count rates for the
two detectors behind an identical calcite at the far away receiver catching
the twin beam from the atomic light source no matter how one moves the
phase plate at the transmitter. Therefore, no communication of useful
messages in the average. However, this system could still be made to work
by a clever analysis of the fluctuations in the receiver count rates - I
think. But it would not be easy.

I then changed the design of the fourth stage by taking both mixed outputs
from the transmitter recombiner - now with the "local unitary" 90 degree
phase shift that all the physicists say is correct - and fed them into a
specially designed single "clamped" (it cannot recoil) transmitter counter.
The quantum equations, in this case, predict a local decoding at the
distant receiver of messages nonlocally encoded by changing the transmitter
phase plate.

In the simplest case, if the receiver crystal and the transmitter crystals
are kept fixed at a relative misalignment of 45 degrees, then the
difference in the receiver photon count rates will be proportional to the
cosine of the variable transmitter phase retardation controlled by moving
the phase plat up or down in time for a continuous stream of photon pairs
from the atomic source placed somewhere between the transmitter and
receiver crystals.  Therefore, we locally decode the message by recording
the changing receiver count rate difference.

Quantum action at a distance is polarizing the receiver light in a
controled way from the transmitter. In the ordinary set up this is
impossible the receiver light and the transmitter light is always
unpolarized - hence no communication.

If you want to picture this process in terms of flowing bits of information
along space-time paths you can. But then it is a three point process not a
two point process. A stream of bits moves backwards in time from the
transmitter to the atoms emitting the the photon pairs at exactly the
moments that the pairs are emitted. This message from the future
transmitter phase plate setting is impressed upon the receiver photon which
is then passively analyzed by the receiver crystal. Therefoe, it is easy to
see that the Einstein space-time separation between transmitter detection
and receiver detection events for two photons in the same pair doesn't
matter. That's why its an observable pre-geometry effect. There is no
stream of information-bearing energy flow directly between transmitter and
receiver as with ordinary signalling.

It's this totally new idea (first given by Professor de Beauregard at the
Intitute Henri Poincare in Paris) implicit in the old Wheeler-Feynman-
Fokker-Hoyle-Narlikar electrodynamics that confuses physicists.

In the delayed choice mode in which the source is closer to the receiver
than to the transmitter, precognitive messages from the future are
received. One can design a system so that the transmisstion is in the
frame-invariant time-like future of the reception of the message. This is a
"loop in time" of the quantum force of destiny. It leads to the sort of
"global-self consistency" discussed by Kip Thorne, Igor Novikov et-al as
popularly described in John Gribbon's new book, UNVEILING THE EDGE OF TIME.
