论文摘要
在本文中，我们通过证明一些结果并提供最适用的实例来研究对角线量子通道及其结构。首先，结果表明，每个对角线量子通道从计算基础上对纯状态的作用是由某些过渡概率确定的纯状态的凸组合。最后，通过使用Cholesky分解，就提出了一种算法方法，以找到对角量子通道的Kraus操作员的明确形式。
In this paper we study diagonal quantum channels and their structure by proving some results and giving most applicable instances of them. Firstly, it is shown that action of every diagonal quantum channel on pure state from computational basis is a convex combination of pure states determined by some transition probabilities. Finally, by using the Cholesky decomposition it is presented an algorithmic method to find an explicit form for Kraus operators of diagonal quantum channels.
