文摘

Using Einstein–Podolsky–Rosen–Bohm experiments as an example, we demonstrate that the combination of a digital computer and algorithms, as a metaphor for a perfect laboratory experiment, provides solutions to problems of the foundations of physics. Employing discrete-event simulation, we present a counterexample to John Bell’s remarkable “proof” that any theory of physics, which is both Einstein-local and “realistic” (counterfactually definite), results in a strong upper bound to the correlations that are being measured in Einstein–Podolsky–Rosen–Bohm experiments. Our counterexample, which is free of the so-called detection-, coincidence-, memory-, and contextuality loophole, violates this upper bound and fully agrees with the predictions of quantum theory for Einstein–Podolsky–Rosen–Bohm experiments.
