Symmetric quantum correlations and properties have been often investigated earlier in the process of quantum decoherence. However, the asymmetric quantum features, such as steering, have been rarely considered in this context. In this work, we study Einstein–Podolsky–Rosen steering, measured by steering robustness R, for two-qubit systems under asymmetric noise channels. For the one-sided asymmetric noise channels, we explore the influence of several typical channels on the asymmetric decay of steering. Our results show that the asymmetric steering is directly linked to the initial state as well as the type of noises. We prove that asymmetric decay can be used to characterize the properties of the channels in some certain. For the two-sided asymmetric noise channels, the results show that the behavior of steering are also both initial states and combination types depended. Moreover, we show that there always exist asymmetric steering even the initial state is high symmetry for the depolarizing-amplitude damping combination channel.

对称量子相关性和性质经常在量子退相干过程中进行过较早的研究。但是，在这种情况下，很少考虑非对称量子特征，例如操纵。在这项工作中，我们研究了爱因斯坦-波多尔斯基-罗森转向，通过转向鲁棒性R来衡量，适用于非对称噪声信道下的两个量子比特系统。对于单侧非对称噪声通道，我们探索了几种典型通道对转向非对称衰减的影响。我们的结果表明，非对称转向与初始状态以及噪声的类型直接相关。我们证明不对称衰减可以用来确定通道的某些特性。对于两侧非对称噪声通道，结果表明转向的行为也取决于初始状态和组合类型。此外，我们表明，去极化-振幅阻尼组合通道即使初始状态具有高对称性，也始终存在非对称转向。
