使用Quantum Helper压缩源代码

Source Compression with a Quantum Helper

Min-Hsiu Hsieh, Shun Watanabe

摘要:

我们研究了具有量子边信息的经典信源编码,其中量子边信息由辅助者观察并通过经典信道发送到解码器。我们推导出一个单字母表征的可实现的速率区域这个问题。结果的直接部分由Winter的测量压缩理论证明。我们的结果表明,一个助手的计划,分别进行测量和压缩是次优的,测量压缩是从根本上需要实现最佳速率区域。

英文摘要:

We study classical source coding with quantum side-information where the quantum side-information is observed by a helper and sent to the decoder via a classical channel. We derive a single-letter characterization of the achievable rate region for this problem. The direct part of our result is proved via the measurement compression theory by Winter. Our result reveals that a helper's scheme that separately conducts a measurement and a compression is suboptimal, and the measurement compression is fundamentally needed to achieve the optimal rate region.
