A Local Realist Account of the Weihs et al EPRB Experiment
Donald A. Graft

TL;DR
This paper proposes a local realistic interpretation of the Weihs et al EPRB experiment, arguing that experimental results indicating nonlocal entanglement are misinterpreted and can be explained without nonlocality, thus reconciling quantum mechanics with local realism.
Contribution
It introduces a local realistic model that accounts for EPRB experiments by emphasizing the importance of device calibration, challenging the standard interpretation of nonlocal entanglement.
Findings
The local model can replicate quantum and classical results through parameter adjustments.
Experimental evidence for nonlocal entanglement may be a misinterpretation due to calibration issues.
Quantum mechanics remains valid as a probability calculus despite the local realistic reinterpretation.
Abstract
Quantum mechanics stands in conflict with local realism only in its treatment of separated systems. A modification of quantum mechanics that changes the handling of separated systems is suggested that can reconcile quantum mechanics with local realism. An apparent obstacle to this program is the experimental evidence, but I argue that the experiments have been misinterpreted. By way of example, I describe a local realistic account of one important EPRB experiment that is claimed to demonstrate nonlocal entanglement. The local model can be calibrated into both quantum and classical domains via adjustment of parameters of the apparatus. Weihs incorrectly dismisses these parameters as uncritical, whereas we show that device calibration is crucial. When properly interpreted, the experiments show that nonlocal entanglement is an error. The rest of quantum mechanics remains intact, and…
