Lecture WS 21/22 Foundation of quantum mechanics

This lecture shows how the laws of quantum mechanics follow from the basic law for expectation values in classical statistics. The description of our world is probabilistic, but needs no concepts beyond the standard rules for probabilities. The “mysteries” of quantum mechanics find their explanation in the correlations of classical statistical systems. We describe explicitly simple classical statistical systems in terms of wave functions and non-commuting operators for observables. They can obey a unitary time evolution and realise entanglement.
