论文摘要
引入了一组多级振幅阻尼（MAD）量子通道，作为标准量子振幅阻尼通道的概括性限制，以有限尺寸$ d $的量子系统。在$ d = 3 $的特殊情况下，通过利用可降解性，数据处理不平等和渠道同构，我们为相当宽的地图计算了相关的量子和私人经典能力，从而扩展了到目前为止已知已知的一组可解决的模型。然后，我们继续评估纠缠辅助，量子和经典能力。
The set of Multi-level Amplitude Damping (MAD) quantum channels is introduced as a generalization of the standard qubit Amplitude Damping Channel to quantum systems of finite dimension $d$. In the special case of $d=3$, by exploiting degradability, data-processing inequalities, and channel isomorphism, we compute the associated quantum and private classical capacities for a rather wide class of maps, extending the set of solvable models known so far. We proceed then to the evaluation of the entanglement assisted, quantum and classical, capacities.
