This special issue gives us the chance to focus on meaningful interaction fields, which are not only possible, but also often necessary. Our aim is to point out many relevant similarities in our disciplines, in spite of the relative different languages and theories we use. Moreover, we would like to find the areas where new instruments and technologies are necessary, to give a new energy to a quite immobile research. Even if this research seems quite far from quantum information, we will try to show you that your questions are closer to what we are studying. Thanks to an extremely specific approach, special issue points out relevant themes, also for humanities faculties. We will consider the relation between communication models and learning/teaching ones; both in communication and in learning, the transmissive model has changed into the interactive model. The methods and technologies we have are not always satisfactory. That is why this special issue seems so interesting to us.
