This Defense Intelligence Reference Document (DIA-08-1003-016), dated 30 March 2010 and produced by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) Program, reviews quantum entanglement and nonlocality. It asks whether they could carry observer-to-observer signals faster than light or backward in time, with real-time control of a Mars rover as an example. It finds no compelling answer yet and says the question must be settled by experiment.

The left-going offer waves pass through both slits of 52, where the waves are combined and detected by the center detector (circled). The momentum-entangled right-going offer waves pass through the both slits of S1, which are the optical images of S2, and interfere at the camera. Confirmation waves return, and the two-slit transaction forms. Therefore, from the point of view of the transactional interpretation of quantum mechanics (Reference 19), the nonlocal connection between detection events at the two ends of the experiment arises because the detection transactions for the two entangled photons must share a "two-way handshake" at the nonlinear crystal, a condition that can be realized only when the summed vector momenta of the two photons equals that of the pump-laser photon that created them. This view explains Dopfer's observations (Reference 19) and indicates that, in the absence of overwhelming noise or restrictions imposed by coherence/entanglement complementarity, no coincidence should be required between the two detectors in the experiment to observe that change in the pattern observed at D1 when detector D2 is moved. This remains true in the configurations discussed below, when slit S2 is lengthened with many kilometers of fiber-optic light transmission cable to enable superluminal and retrocausal signal transmission. In other words, analysis of the nonlocal communication test system with the transactional interpretation reveals no "show-stopper" aspects that would prevent superluminal and retro-causal signal transmission. The transactional interpretation is neutral on whether such signals are possible. 16 UNCLASSIFIED//J;QII. 8Ffllil*le 1!191! Ohl I
