标题： SeCQC: An open-source program code for the numerical Search for the classical Capacity of Quantum Channels

摘要： SeCQC 是一个开源程序代码，通过使用迭代方法实现对量子信道的经典容量的数值搜索（SeCQC）。 给定一个量子信道，SeCQC 找到使可获得信息最大化的统计算子和 POVM 结果，从而确定量子信道的经典容量。 优化过程通过使用沿着 POVM 空间梯度的最速上升方法实现，同时也使用共轭梯度法以加快速度。 显示英文摘要

摘要： SeCQC is an open-source program code which implements a Numerical Search for the classical Capacity of Quantum Channels (SeCQC) by using an iterative method. Given a quantum channel, SeCQC finds the statistical operators and POVM outcomes that maximize the accessible information, and thus determines the classical capacity of the quantum channel. The optimization procedure is realized by using a steepest-ascent method that fol- lows the gradient in the POVM space, and also uses conjugate gradients for speed-up.
