Abstract
We show that the minimum von Neumann entropy output of a quantum channel is locally additive. Hastings´ counterexample for the additivity conjecture makes this result quite surprising. In particular, it indicates that the nonadditivity of the minimum entropy output is a global effect of quantum channels.
