Abstract

We present a comprehensive characterization of the interconnections between single-mode, phase-insensitive Gaussian Bosonic Channels resulting from channel concatenation. This characterization enables us to identify, in the parameter space of these maps, two distinct regions: low-ground and high-ground. In the low-ground region, the information capacities are smaller than a designated reference value, while in the high-ground region, they are provably greater. As a direct consequence, we systematically outline an explicit set of upper bounds for the quantum and private capacity of these maps, which combine known upper bounds and composition rules, improving upon existing results.

玻色高斯信道的低地/高地容量区域分析
我们全面描述了通道连接产生的单模、相位不敏感高斯玻色通道之间的互连。这种表征使我们能够在这些映射的参数空间中识别出两个不同的区域:低地和高地。在低地区域,信息容量小于指定的参考值,而在高地区域,信息容量明显大于指定的参考值。作为直接结果,我们系统地概述了这些映射的量子容量和私人容量的一组明确上限,它们结合了已知上限和组成规则,改进了现有结果。
