    "abstract": "A framework for a quantum information theory is introduced that is based on\nthe measure of quantum information associated with probability distribution\npredicted by quantum measuring of state. The entanglement between states of\nmeasured system and \"pointer\" states of measuring apparatus, which is generated\nby dynamical process of quantum measurement, plays a dominant role in\nexpressing quantum characteristics of information theory. The quantum mutual\ninformation of transmission and reception of quantum states along a noisy\nquantum channel is given by the change of quantum measured information. In our\napproach, it is not necessary to purify the transmitted state by means of the\nreference system. It is also clarified that there exist relations between the\napproach given in this letter and those given by other authors.",
