  The experiments reported in this paper were carried out with space-separated
entangled thermoluminescent dosimetry (TLD) crystals in Baton Rouge, Louisiana
(USA) and Givarlais (France) at 8,182 km between entangled samples. Samples
consisted of doped lithium fluoride TLD's that were simultaneously irradiated
in pairs together at one location by Bremsstrahlung radiation generated by a
Varian CLINAC unit. One of the paired TLD crystals was then mailed to Baton
Rouge and its entangled counterpart remained in Givarlais. The crystal in Baton
Rouge (master) was then subjected to thermal stimulation which elicited a
measurable light emission response in the counterpart (slave) under a
photomultiplier in Givarlais. Highly correlated passive light emissions were
observed in the nonheated slave TLD while the master TLD was ramped up in
temperature and then allowed to cool to ambient temperature. Maximum
correlations in the slave TLD light emissions were observed at the turn around
temperature which is the point where the master TLD temperature is allowed to
decrease. The experimenter in Girvalais was thus able to determine with high
accuracy the point in time at which the master TLD heating oven was turned off
(turn around point) without any communication between the experimenters during
the heating-cooling phase of the experiment. The implications of these observed
results are of great significance for quantum communication technology.
