NOISE AND BELL’S INEQUALITY

摘要

To many, the idea of the EPR paradox and the possibility of local hidden variables werendismissed by the Bell inequality, although the central points of this argument have beennaround since the advent of quantum mechanics. Yet, there remains considerable evidencenthat this inequality can be violated even by classical systems. The question really isnwhether or not strongly correlated classical fields will also violate Bell’s inequality. In anprevious paper, it was shown that this was the case. Here, we ask the question as to justnhow much correlation in the classical waves is required to violate the inequality.
