玻色广播信道的经典信息容量

Classical Information Capacity of the Bosonic Broadcast Channel

Saikat Guha, Jeffrey H. Shapiro

摘要:

我们表明,当相干状态编码与相干检测相结合,玻色子广播信道是相当于一个经典的退化高斯广播信道的容量区域是双重的经典高斯多址接入信道。我们进一步表明,如果一个最小输出熵猜想成立,那么最终的经典信息容量的玻色子广播信道可以实现的相干状态编码。我们提供了一些证据来支持这一猜想。

英文摘要:

We show that when coherent-state encoding is employed in conjunction with coherent detection, the Bosonic broadcast channel is equivalent to a classical degraded Gaussian broadcast channel whose capacity region is dual to that of the classical Gaussian multiple-access channel. We further show that if a minimum output-entropy conjecture holds true, then the ultimate classical information capacity of the Bosonic broadcast channel can be achieved by a coherent-state encoding. We provide some evidence in support of the conjecture.
