Nicolas Boulant, Lorenza Viola, Evan M. Fortunato, David G. Cory

摘要:

级联编码为量子信息存储和传输提供了一种通用的噪声保护策略。我们报告的实施级联量子纠错码能够纠正相位误差与强相关的组件。该实验使用液态核磁共振技术在标记巴豆酸的四自旋子系统上进行。我们的研究结果表明,主动和被动量子纠错码之间的级联提供了一个实用的工具来处理现实的噪声贡献的独立和相关的错误。

英文摘要:

Concatenated coding provides a general strategy to achieve the desired level of noise protection in quantum information storage and transmission. We report the implementation of a concatenated quantum error-correcting code able to correct against phase errors with a strong correlated component. The experiment was performed using liquid-state nuclear magnetic resonance techniques on a four spin subsystem of labeled crotonic acid. Our results show that concatenation between active and passive quantum error-correcting codes offers a practical tool to handle realistic noise contributed by both independent and correlated errors.
