    "abstract": "Let us consider two quantum systems: system A and system B. Suppose that a\nclassical information is encoded to quantum states of the system A and we\ndistribute this information to both systems by making them interact with each\nother. We show that it is impossible to achieve this goal perfectly if the\nstrength of interaction between the quantum systems is smaller than a quantity\nthat is determined by noncommutativity between a Hamiltonian of the system A\nand the states (density operators) used for the information encoding. It is a\nconsequence of a generalized Winger-Araki-Yanase theorem which enables us to\ntreat conserved quantities other than additive ones.",
