我们证明了由Luo和Yanagi证明的与Wigner-Yanase-Dyson信息相关的不确定关系对于任意量子Fisher信息不成立。我们表明，通过改变一个常数，一个类似的迹不等式持有充分的一般性。
We show that an uncertainty relation proved by Luo and Yanagi and related to Wigner–Yanase–Dyson information cannot hold for an arbitrary quantum Fisher information. We show that, by changing a costant, a similar trace inequality holds in full generality.
