Hypothesis testing and Stein's lemma in general probability theories with Euclidean Jordan algebra and its quantum realization
Kanta Sonoda, Hayato Arai, Masahito Hayashi
Even though quantum information theory gives advantage over classical information theory, these two information theories have a structural similarity that many exponet rates of inf…

Quantum Implementation of Non-Positive-Operator-Valued Measurements in General Probabilistic Theories by Post-Selected POVMs
Hayato Arai, Masahito Hayashi
It is important problem to clarify the class of implementable quantum measurements from both fundamental and applicable viewpoints. Positive-Operator-Valued Measure (POVM) measurem…
