Abstract: | After analyzing the difficulties for a local realistic interpretation of quantum theory, it is argued that such an interpretation might be possible if some new postulates are added to the standard ones. We propose a stochastic interpretation of quantum theory, which involves the need of joint probability distributions for all relevant observables. The well known problems for the existence of joint distributions are solved by assuming that neither all Hermitian operators correspond to observables nor all density matrices represent physical states. A research program along these lines is presented studying in particular the Maxwell quantum field and the Dirac field. |
