Maximal rank of extremal marginal tracial states
Hiromichi Ohno
States on coupled quantum system whose restrictions to each subsystems are normalized traces are called marginal tracial states. We investigate extremal marginal tracial states and…

Quantum Markov fields on graphs
Luigi Accardi, Hiromichi Ohno, Farrukh Mukhamedov
We introduce generalized quantum Markov states and generalized d-Markov chains which extend the notion quantum Markov chains on spin systems to that on -algebras defined by ge…

Relation between the Dynamics of the Reduced Purity and Correlations
Gen Kimura, Hiromichi Ohno, Milan Mosonyi
A general property of the relation between the dynamics of the reduced purity and correlations is investigated in quantum mechanical systems. We show that a non-zero time-derivativ…
