In this work, we use the Shannon informational entropies to study an electronconfined in a double quantum dot; we mean the entropy in the space ofpositions, $S_r$, in the space of momentum, $S_p$, and the total entropy, $S_t= S_r+S_p$. We obtain $S_r$, $S_p$ and $S_t$ as a function of the parameters$A_2$ and $k$ which rules the height and the width, respectively, of theinternal barrier of the confinement potential. We conjecture that the entropy$S_r$ maps the degeneracy of states when we vary $A_2$ and also is an indicatorof the level of decoupling/coupling of the double quantum dot. We study thequantities $S_r$ and $S_p$ as measures of delocalization/localization of theprobability distribution. Furthermore, we analyze the behaviors of thequantities $S_p$ and $S_t$ as a function of $A_2$ and $k$. Finally, we carriedout an energy analysis and, when possible, compared our results with workpublished in the literature.
