    "abstract": "An elementary introduction into algebraic approach to unified quantum\ninformation theory and operational approach to quantum entanglement as\ngeneralized encoding is given. After introducing compound quantum state and two\ntypes of informational divergences, namely, Araki-Umegaki (a-type) and of\nBelavkin-Staszewski (b-type) quantum relative entropic information, this paper\ntreats two types of quantum mutual information via entanglement and defines two\ntypes of corresponding quantum channel capacities as the supremum via the\ngeneralized encodings. It proves the additivity property of quantum channel\ncapacities via entanglement, which extends the earlier results of V. P.\nBelavkin to products of arbitrary quantum channels for quantum relative entropy\nof any type.",
