任意信源、信道和纠缠源的量子编码定理

Quantum Coding Theorems for Arbitrary Sources, Channels and Entanglement Resources

Garry Bowen, Nilanjana Datta

摘要:

信息谱方法给出了各种信息理论协议的最优速率的一般公式,在最小的假设下,对所涉及的源,信道和纠缠资源的性质。本文的高潮是在推导的密集编码容量的无噪声量子信道,辅助任意共享纠缠,使用这种方法。我们还回顾了目前已知的编码定理,和他们的逆,如任意量子源的数据压缩和经典信息通过任意量子信道的传输协议。此外,我们还推导出了混合信源的最优数据压缩率

英文摘要:

The information spectrum approach gives general formulae for optimal rates of various information theoretic protocols, under minimal assumptions on the nature of the sources, channels and entanglement resources involved. This paper culminates in the derivation of the dense coding capacity for a noiseless quantum channel, assisted by arbitrary shared entanglement, using this approach. We also review the currently known coding theorems, and their converses, for protocols such as data compression for arbitrary quantum sources and transmission of classical information through arbitrary quantum channels. In addition, we derive the optimal rate of data compression for a mixed source
