中文摘要：

阐述的是当ρ为3维复Hilbert空间中不相干的密度算子时,Skew information单调递减,且在2维的量子体系中Skew information是单调递减的启发下继续讨论其单调性.

英文摘要：

In this paper,we propose skew information can decrease under a class of incoherent operations in the three-dimensional Hilbert space.And it is following the framework of skew information decrease under non-selective quantum measurement for two-dimensional quantum systems.
