Title: Three levels of Bell’s inequalities.
Abstract. Bell’s inequalities can be discussed at three different levels: using classical probabilities, classical conditional probabilities, and quantum probabilities. In the talk I will show that the violation of Bell’s inequalities have a clear meaning on the first two levels: on the first level it rules out the probabilistic interpretation of certain events; on the second level it rules out a common cause type explanation of certain correlations. However, the interpretation of Bell’s inequalities applied in quantum field theories is not so obvious.
