Extension of the postulational basis of quantum theory by introducing correlations between the results of measurements, leads to negative joint probabilities for otherwise meaningful sets of measured values. Since the attempt made is probably the only one compatible with the theory of random variables, and is incompatible with the structure of Hilbert space, it is concluded that correlations are absent. This result, though it is tantamount to a denlal of von Neumann's projection postulate and…

A quantitative comparison between both schemes is established in terms of the amount of coherence present in the initial state of the system, as quantified by the l1-coherence measure, and it is proved that the average entropy production can take negative values in the Margenau–Hill framework.
