摘要

不确定性关系揭示了经典世界与量子世界之间的内在差异。我们研究了量子比特系统中量子信道的量子不确定性关系。在两种一般测量基础下，我们首先推导出量子信道相对于相干熵的量子不确定性关系。然后，我们得到了单位通道的量子不确定性与相干性的（l_1\）规范的关系。我们详细给出了一些例子。

The quantum uncertainty relations of quantum channels

The uncertainty relation reveals the intrinsic difference between the classical world and the quantum world. We investigate the quantum uncertainty relation of quantum channel in qubit systems. Under two general measurement bases, we first derive the quantum uncertainty relation for quantum channels with respect to the relative entropy of coherence. Then we obtain the quantum uncertainty relation for unitary channels with respect to the \(l_1\) norm of coherence. Some examples are given in detail.
