量子信道的编码定理

Coding Theorems for Quantum Channels

Alexander S. Holevo

摘要:

在过去的几年里,量子通信信道的(经典)信息容量的30多年的老问题得到了戏剧性的澄清,当时发现了一些直接量子编码定理。本文件给出了一个自我包含的治疗的主题,以下尽可能多的平行与经典的信息理论,并在另一方面,强调深刻的差异的量子情况。重点介绍了最近的一些结果,如包括无限(可能连续)字母和约束输入情形的一般量子编码定理,纯态信道和量子高斯信道的可靠性函数。简要概述了几个尚未解决的问题。

英文摘要:

The more than thirty years old issue of the (classical) information capacity of quantum communication channels was dramatically clarified during the last years, when a number of direct quantum coding theorems was discovered. The present paper gives a self contained treatment of the subject, following as much in parallel as possible with classical information theory and, on the other side, stressing profound differences of the quantum case. An emphasis is made on recent results, such as general quantum coding theorems including cases of infinite (possibly continuous) alphabets and constrained inputs, reliability function for pure state channels and quantum Gaussian channel. Several still unsolved problems are briefly outlined.
