This paper advances fundamental quantum theory by establishing a Perron-Frobenius-type theorem for periodic sequences of ergodic quantum channels in disordered settings. It provides rigorous mathematical generalizations of prior work on spectral data, offering deeper theoretical insights relevant to quantum information and dynamical systems research.
Periodicity in Ergodic Quantum Processes
arXiv:2604.09422v2 Announce Type: replace-cross Abstract: We study the periodic properties of sequences of quantum channels sampled from an ergodic stochastic process satisfying a natural irreducibility condition. We relate these periodic properties to certain global spectral data defined by the sequence of quantum channels, proving a general Perron-Frobenius-type theorem that in particular constitutes a full generalization of the work of Evans and H{\o}egh-Krohn to the disordered setting.
