论文摘要
我们考虑在可用的显式密度矩阵描述的情况下有效计算Uhlmann保真度的问题。我们得出了一个替代公式，更简单地评估数值，为大型矩阵节省了10倍。
We consider the problem of efficiently computing the Uhlmann fidelity in the case when explicit density matrix descriptions are available. We derive an alternative formula which is simpler to evaluate numerically, saving a factor of 10 in time for large matrices.
