量子Turbo码

量子纠错编码技术在量子通信和量子计算领域起着非常重要的作用.构造量子纠错编码的主要方法是借鉴经典纠错编码技术,目前几乎所有经典纠错编码方案都已经被移植到量子领域中来,然而在经典编码领域纠错性能最杰出的Turbo码却至今没有量子对应.提出了一种利用量子寄存器网络构造量子递归系统卷积码的简单实现方案,同时利用量子SWAP门设计了一种高效的量子交织器门组网络方案.最后仿照经典Turbo码的设计原理提出串行级联的量子Turbo码,同时提出了可行的译码方法.量子Turbo码不仅丰富了量子纠错码研究的领域,同时为解释 关键词： 量子递归系统卷积码 量子Turbo码 量子纠错编码 量子信息

Quantum Turbo codes

Quantum error correction coding technology is of great importance for quantum communication as well as quantum computation.Nearly all of the classical error correction coding schemes have, for the time being, been transplanted to the domain of quantum information;nevertheless, the most outstanding scheme in classical coding region, turbo code,still lacks the quantum analogy till now.We have completed a simple scheme of quantum recursive systematic convolutional code by means of quantum register network.At the same time, a kind of efficient quantum interweaver is constructed using only quantum SWAP gates.Also a serially concatenated quantum Turbo code is developed by analogy to the classical Turbo code.As limited by the quantum non-cloning theorem, the proposed quantum turbo code is serially concatenated.Quantum turbo code may not only extend the research area of quantum error correction coding technology, but also solve the puzzle in classical coding theory.
