摘　　要：文献(XIE C M,LIU Y M,LI G F,et al.A note on quantum correlations in Werner states under two collective noises[J].Quantum Inf Process,2014,13:2713-2718)研究了移相噪声和旋转噪声对量子二元Werner态量子关联的影响,发现这两种噪声作用下量子二元Werner态量子关联守恒.该文研究这两种噪声(移相噪声和旋转噪声)对量子三元Werner态量子关联的影响,结果显示这两种噪声不改变量子三元Werner态中的量子关联,换句话说,量子三元Werner态具有抵抗这两种噪声的特性.The reference（XIE C M,LIU Y M,LI G F,et al.A note on quantum correlations in Werner states under two collective noises[J].Quantum Inf Process,2014,13：2713-2718）investigated the influences of dephasing noise and rotating noise on quantum correlation in qubit Werner states and found that the quantum correlation was invariable.In this paper,the influences of the same two collective noises,i.e.,dephasing noise and rotating noise,on quantum correlations in qutrit Werner states were studied.It was found that the collective noise don’t alter the quantum correlations in qutrit Werner states as well.In other words,quantum correlations in qutrit Werner states were robust against the noise,too.
