量子费舍尔信息的不等式

Inequalities for quantum Fisher information

Paolo Gibilisco, Daniele Imparato, Tommaso Isola

摘要:

2003年,Luo证明了Wigner-Yanase信息与$SLD$ -信息之间的一个不等式.本文证明了Luo不等式是一个一般不等式的特殊情况,该不等式对任何正则量子费舍尔信息都成立。此外,我们表明,这个一般的不等式是一个后果的Kubo-Ando不等式,指出任何矩阵的平均值大于调和平均值,小于算术平均值。

英文摘要:

In 2003 Luo proved an inequality relating the Wigner-Yanase information and the $SLD$-information. In this paper we prove that Luo's inequality is a particular case of a general inequality which holds for any regular quantum Fisher information. Moreover we show that this general inequality is a consequence of the Kubo-Ando inequality that states that any matrix mean is bigger than the harmonic mean and smaller than the arithmetic mean.
