Time evolution of randomness in Bell's experiment indicates 'Realism' is false

Abstract: WWe measure time evolution of Minimum Entropy and (estimated) Kolmogorov's Complexity of binary time series during short pulses in a specially designed optical Bell's experiment. We compare evolution between the cases with stations placed close and separated 24m in straight line. This provides a clue about which one of the hypotheses necessary for the derivation and observation of Bell's inequalities is false. This is a foundational problem that has consequences in the field of random numbers' generation. Our results are consistent (95% statistical significance) with falsity of 'Realism' as defined to derive the Bell's inequalities, in agreement with the Copenhagen interpretation of Quantum Mechanics. Unrelated to the foundational problem, our observations have practical impact on the efficient use of quantum Random Number Generators and Quantum Key Distribution devices.
