Resumo
This work has the goal to treat the concept of correlation on both classical and quantum, addressing what
already exists about the matter and giving a new perspective about it. Beyond this, we propose a new
manner to calculate the amount of information of a quantum system. For this, the EPR paradox, Bell
theorem, entanglement concept, Shannon and von Neumann entropies, code theory and the quantum
correlation measure so-called quantum discord will be discussed. From those subjects, two generalizations
will be proposed: of the von Neumann entropy and the quantum correlation concept. Some features e
properties will be discussed about these new definitions, however there is still much to be investigated about
its implications.
