Abstract(in Japanese) (See Japanese page)
Abstract(in English) In the theory of quantum information spectrum methods, the divergence spectral rate and the entropy spectral rate play an important role. The divergence spectral rate is defined as a kind of limit on the likelihood ratio of probability distributions and quantum states, and in very general situations, coding rates and error probabilities are expressed in terms of the divergence spectral rate. On the other hand, it is difficult to calculate the divergence spectral rate as a concrete value, except for i.i.d. states and their mixed states. In this study, we investigate the conditions under which the divergence spectral rate and the divergence rate coincide. We consider states with factorization property, such as the Gibbs states and the finitely correlated states in one-dimensional spin chains, and study several conditions under which the divergence rate and the divergence spectral rate coincide.
