Distinguishability Measures and Entropies for General Probabilistic Theories

As a part of the construction of an information theory based on general probabilistic theories, we propose and investigate the several distinguishability measures and “entropies” in general probabilistic theories. As their applications, no-cloning theorems, information-disturbance theorems are reformulated, and a bound of the accessible informations is discussed in any general probabilistic theories, not resorting to quantum theory.
