Titolo: |
THE GEOMETRIC FORMULATION OF QUANTUM STATISTICS AND MEASURES OF
QUANTUM INFORMATION |
Abstract: |
The notion of "metric adjusted skew information"
provides a link between quantum information theory and
the theory of measures of quantum information initiated by Wigner,
Yanase and Dyson. The relationship is made tangible by several
classification theorems for special classes of operator monotone
functions, and they provide us with explicit formulae for the
common used measures of quantum information. As an application it
is shown that the newly introduced Chen-Luo skew information is
convex. |
