论文摘要
我们根据（量子）渔民信息的概念引入了针对量子通道的新不兼容标准。我们的构建基于H.〜zhu提出的量子测量的类似标准。然后，我们在不同情况下研究不兼容标准的力量。首先，我们证明了两个Schur通道不兼容的第一个分析条件。然后，我们研究了去极化通道的元组的不兼容结构，将新引入的标准与不对称量子克隆的已知结果进行了比较。
We introduce a new incompatibility criterion for quantum channels, based on the notion of (quantum) Fisher information. Our construction is based on a similar criterion for quantum measurements put forward by H.~Zhu. We then study the power of the incompatibility criterion in different scenarios. Firstly, we prove the first analytical conditions for the incompatibility of two Schur channels. Then, we study the incompatibility structure of a tuple of depolarizing channels, comparing the newly introduced criterion with the known results from asymmetric quantum cloning.
