UNCLASSIFIED / /®@R-@5Ft6EA1-UGE-ONEY The Space-Communication Implications of Quantum Entanglement and Nonlocality Foreword and Introduction This paper reviews quantum entanglement and nonlocality and considers the possibility that this phenomenon could be used for sending observer-to- observer signals. Such a demonstration would break several quantum “no- signal theorems” in the physics literature. Nonlocal quantum signaling would have far-reaching implications as an enabling technology for superluminal and retrocausal signaling. Scenarios that might lead to nonlocal quantum communication are…

UNCLASSIFIED / / P@R"OPPPCEAUSE-ONLY paper attempts to address these questions by taking a close look at quantum entanglement, quantum nonlocality, the experiments that have explored them, and proposed experiments to test the causal and faster-than-light communication issues evoked by such physics. Quantum entanglement describes the condition of separated parts of the same quantum system in which each of the parts can be described only by referencing the state of other parts. This is one of the most counterintuitive aspects of quantum mechanics, because classically one would expect system part…

UNCLASSIFIED / E02. DEhLGhASE-ONE I. Quantum Entanglement, Nonlocality, and EPR Experiments In the quantum mechanical description of elementary entities like photons, there is a duality between the description as a particle and as a wave. Photons can be thought of as traveling through space as waves but delivering energy (and other conserved quantities) at detection as particles. By choosing the kinds of measurements made on such objects, one can force wave-like or particle-like behavior to be exhibited in the measurements results. Between the entangled parts of a quantum system (for example, …

UNCLASSIFIED / --@R-@F5265t1-USE-ONE-= implications of this dichotomy are considered in the context of the “no-signal” theorems. It is noted that there is some misinformation in the literature concerning the chronology of successful EPR polarization correlation experiments, and here we wish to set the record at least somewhat straighter. The experimental measurement that first demonstrated a polarization correlation related to EPR nonlocality was performed by C. S. Wu and I. Shanknov in 1949 (Reference 7), well before Bell’s work and the subsequent interest in testing Bell’s Inequality. Wu and…
