Conditions for Large-Sample Majorization of Pairs of Flat States in Terms of -z Relative Entropies
Frits Verhagen, Marco Tomamichel, Erkka Haapasalo
We offer the first operational interpretation of the -z relative entropies, a measure of distinguishability between two quantum states introduced by JakÅ¡iÄ et al. and Audenae…

Multivariate Rényi divergences characterise betting games with multiple lotteries
Andrés F. Ducuara, Erkka Haapasalo, Ryo Takakura
We provide an operational interpretation of the multivariate Rényi divergence in terms of economic-theoretic tasks based on betting, risk aversion, and multiple lotteries. We show…

Barycentric decompositions for extensive monotone divergences
Erkka Haapasalo
We study sets of divergences or dissimilarity measures in a generalized real-algebraic setting which includes the cases of classical and quantum multivariate divergences. We show t…
