    "abstract": "The notion of distinguishability between quantum states has shown to be\nfundamental in the frame of quantum information theory. In this paper we\npresent a new distinguishability criterium by using a information theoretic\nquantity: the Jensen-Shannon divergence (JSD). This quantity has several\ninteresting properties, both from a conceptual and a formal point of view.\nPrevious to define this distinguishability criterium, we review some of the\nmost frequently used distances defined over quantum mechanics\u0027 Hilbert space.\nIn this point our main claim is that the JSD can be taken as a unifying\ndistance between quantum states.",
