  In a previous paper, we showed how entanglement of formation can be defined
as a minimum of the quantum conditional mutual information (a.k.a. quantum
conditional information transmission). In classical information theory, the
Arimoto-Blahut method is one of the preferred methods for calculating extrema
of mutual information. In this paper, we present a new method, akin to the
Arimoto-Blahut method, for calculating entanglement of formation. We also
present several examples computed with a computer program called Causa Comun
that implements the ideas of this paper.
