概要
- 論文の詳細を見る
It is shown by way of examples that the quantum correspondent to Fisher information in statistics named quantum information metric is an extensive quantity in spite of the nonextensivity of the quantum q-deformed relative entropy. A general proof is presented, and some related topics on the quantum relative entropies vs the metrics are discussed.
