Research Abstract

Aiming at establishing quantum information geometrical methods in noncommutative statics, we have obtained the following results : 1) Strong consistency and asymptotic efficiency for adaptive quantum estimation problems. 2) Geometry of optimal estimation scheme for SU(D) channels. 3) Randomness criteria in terms of α-divergences. 4) A fibre bundle over manifolds of quantum channels and its application to quantum statistics. 5) Information geometry of Ising spin chains.
