与传统的量子信道表示（如算符和或幺正表示）中的多对一和二次对应性质相反，我们提出了量子信道的一对一和线性（仿射）参数化。这种参数化使我们能够可视化量子通道空间的凸结构。为了证明它的有用性，我们将其应用到量子二进制信道的分析。[S1050-2947（99）01805-3]。
In contrast to the many-to-one and quadratic nature of correspondence in the conventional representation of quantum channels, such as the operator-sum or the unitary representation, we present a one-to-one and linear (affine) parametrization of quantum channels. This parametrization enables us to visualize the convex structure of the space of quantum channels. To demonstrate its usefulness, we apply it to the analysis of quantum binary channels.
