论文摘要
我们通过对类型方法使用通用的包装引理来得出通用的经典量子叠加编码和通用经典Quantum多访问通道代码。使用我们的经典量词通用叠加代码，我们建立了具有降级消息集的经典 - 量子广播频道的容量区域。我们的通用古典量子量访问通道代码具有两种类型的代码。一个是带有联合解码的代码，另一个是带有单独解码的代码。前者普遍实现了能力区域的角点，而后者普遍实现了能力区域的一般点。将后一个通用代码与量子INF过程的现有结果相结合。 18，246（2019），我们为经典Quantum化合物多访问通道的容量区域建立了一个单字公式。
We derive universal classical-quantum superposition coding and universal classical-quantum multiple access channel code by using generalized packing lemmas for the type method. Using our classical-quantum universal superposition code, we establish the capacity region of a classical-quantum compound broadcast channel with degraded message sets. Our universal classical-quantum multiple access channel codes have two types of codes. One is a code with joint decoding and the other is a code with separate decoding. The former universally achieves corner points of the capacity region and the latter universally achieves general points of the capacity region. Combining the latter universal code with the existing result by Quantum Inf Process. 18, 246 (2019), we establish a single-letterized formula for the capacity region of a classical-quantum compound multiple access channel.
