Local Realistic Models Tested by the EPRB Experiment with Random Variable Analyzers

We carry out an analysis of the output data files of the Einstein-Podolsky-Rosen-Bohm experiment realized with random variable analyzers (Innsbruck, 1998). That experiment was devised to disprove Local Realistic alternatives (to Quantum Mechanics) based on the predictability of the analyzers’ positions. The disproval is not immediate, for the quantum mechanical results can be reproduced even if the probability of guessing the analyzers’ position is small. Our analysis is aimed to determine, in quantitative terms, whether this experiment was able to disprove Local Realism. We conclude that the experiment did disprove Local Realism. In addition, the experiment provides time-resolved data files which allow us to look for privileged frequencies in the spectrum of the time fluctuations. Such privileged frequencies, if existed, could be interpreted as a sign of a non-ergodic behavior. To our knowledge, this is the first time such a study is proposed and performed.
