量子协方差、量子费舍尔信息和不确定原理

Quantum covariance, quantum Fisher information and the uncertainty principle

Paolo Gibilisco, Fumio Hiai, Denes Petz

摘要:

本文研究了量子协方差与量子Fisher信息之间的关系。本研究应用于推广一个最近证明的基于量子费舍尔信息的测不准关系。这里给出的证明大大简化了以前提出的证明,并导致更一般的不等式。

英文摘要:

In this paper the relation between quantum covariances and quantum Fisher informations are studied. This study is applied to generalize a recently proved uncertainty relation based on quantum Fisher information. The proof given hereconsiderably simplifies the previously proposed proofs and leads to more general inequalities.
