Unifying Quantum Non-Locality Tests via Device-Independent Frameworks — E8 Intelligence Research
Andrew Stewart Caldin
Abstract
FINDING: Bell inequality tests confirm quantum non-locality; new generalized rules (Buscemi) unify entanglement tests via device-independent frameworks. MATH: CHSH inequality: \(S = E(a,b) + E(a,b') + E(a',b) - E(a',b') \leq 2\) (local hidden variables); quantum violation max \(S = 2\sqrt{2} \approx 2.828\). Bell's original inequality: \(P(\vec{a},\vec{b}) - P(\vec{a},\vec{c}) \leq 1 + P(\vec{b},\vec{c})\). Buscemi's unification: replaces measurement settings with quantum inputs, yielding semi-device-independent bounds—generalizes to \(S_q \leq 2\sqrt{2}\) for qubits, but for higher-dimensional systems, Tsirelson bounds scale as \(2\sqrt{d}\) for maximally entangled states. CONNECTION: The maximal quantum violation \(2\sqrt{2}\) relates to the golden ratio via \(2\sqrt{2} = 2 \times 1.414\), and \(1.414^2 = 2\)—a Pythagorean doubling. More directly, the CHSH bound \(2\sqrt{2}\) appears in the geometry of the square (diagonal/side ratio), linking to 45° rotations in 2D lattice symme Author: Andrew Stewart Caldin, Independent Researcher, UK.
