This study establishes an exact mathematical limit for how much measurement dependence is required to replicate quantum correlations in CHSH experiments, unifying detector efficiency, Bell inequality violations, and local hidden variable models into a single analytical framework. By deriving precise trade-off surfaces and identifying a moiré phase-locking mechanism, the research provides testable predictions that distinguish fundamental quantum mechanics from classical theories with greater precision than previous approximations allowed.
Researchers Bound Hidden Variable Models Via Measurement Dependence
Can local hidden variable theories ever fully replicate experimental results from CHSH experiments without invoking unrealistically strong correlations between measurement settings and outcomes? This work establishes an exact mathematical relationship defining that limit, quantifying how much dependence on measurement settings is required to achieve any given violation of Bell’s inequality alongside realistic detector inefficiencies. A moiré phase-locking mechanism demonstrates this minimal dependence precisely with perfect detection, offering a testable prediction via subtle fringes in fourfold coincidence sums.
Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), Austria, derived the exact mathematical relationship between measurement dependence, Bell inequality violation, and detector efficiency in CHSH experiments. Aaron Alai used linear programming to prove that the minimum measurement dependence required to reproduce quantum correlations with 90% detector efficiency is '(27√2 − 33)/100'. The study unifies these three factors within a single analytical framework, providing exact trade-off surfaces and experimentally testable predictions for distinguishing local hidden-variable models from quantum…
