AAWSAP DIRD, The Space Communication Implications of Quantum Entanglement and Nonlocality, March 2010

U.S. Department of War · 2010-03-30 · 32 pages · text from the file's own layer

This Defense Intelligence Reference Document, dated 30 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under its Advanced Aerospace Weapon System Applications Program. It reviews quantum entanglement, nonlocality and EPR experiments, and asks whether nonlocal quantum effects could carry observer-to-observer signals faster than light. The paper describes proposed experiments and an example of real-time Earth control of a Mars rover. It concludes that there is no compelling answer yet and that experimental tests are needed.

From the source:Release of 2026-09-18 Incident: 3/30/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD reviews quantum entanglement and nonlocality with a focus on whether those phenomena might be usable as a means of faster-than-light communication between observers, especially for real-time space operations over interplanetary distances. The report surveys the relevant quantum experiments and no-signal theorems, then examines proposed communication schemes based mainly on momentum-entangled photons, including scenarios involving superluminal and retro-causal signaling. However, it repeatedly acknowledges that the central question remains unresolved experimentally, and it gives substantial attention to the coherence-versus-entanglement tradeoff and other features of standard quantum mechanics that may prevent usable signaling even if non-local correlations are experimentally validated. Overall, the document is an exploratory analysis of whether quantum nonlocality could conceivably support a practical communications application rather than a demonstration of prospective utility.

Figure 8. Transactional Interpretation Diagrams for Case 1. The left-going offer waves pass through the
upper slit of 52 and reach the upper detector (circled) . The momentum-entangled right-going offer waves pass only
through the lower slit of 51, which is the optical image of upper 52, and are diffracted to the camera. Confirmation
waves return , and the one-slit transaction forms.
Figure 9 shows t he transaction that forms for the nonlocal communication test system
in the Case 2 configuration. The left-going photon passes through bot h the upper and
lower slits of S2 . The two paths connect to a combiner and are detected by the central
detector (circled). The momentum-entangled right-go ing photon must then also pass
through both slits of S1, which are t he optical images of S2, to form a two-slit
interference pattern detected by the camera . The three stages of transaction formation
are shown.
