Uitati ultimul experiment al grupului de la Viena, oameni care au continuat munca lui Alan Aspect si au demonstrat aproape tot ce era de demonstrat in legatura cu teorema lui Bell :

"
Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster than the speed of light.
Bell's theorem states that this worldview is incompatible with the predictions of quantum mechanics, as is expressed in Bell's inequalities.
Previous experiments convincingly supported the quantum predictions. Yet, every experiment requires assumptions that provide loopholes for a local realist explanation. Here we report a Bell test that closes the most significant of these loopholes simultaneously."
"By closing the freedom-of-choice loophole to one natural stopping point—the first moment at which the particles come into existence—
we reduce the possible local-realist explanations to truly exotic hypotheses." :)
