量子卷积码的描述

Description of a quantum convolutional code

H. Ollivier, J. -P. Tillich

摘要:

我们描述了一个量子纠错方案,旨在保护长距离通信中的量子信息流。它在很大程度上受到经典卷积码理论的启发,经典卷积码在经典通信中用于类似的情况。这里所示的特定示例使用稳定器形式主义,其提供了显式编码电路。一个相关的误差估计算法显式地给出,并示出提供任何无记忆量子信道的最有可能的错误,而其复杂性仅与编码量子比特的数量线性增长。

英文摘要:

We describe a quantum error correction scheme aimed at protecting a flow of quantum information over long distance communication. It is largely inspired by the theory of classical convolutional codes which are used in similar circumstances in classical communication. The particular example shown here uses the stabilizer formalism, which provides an explicit encoding circuit. An associated error estimation algorithm is given explicitly and shown to provide the most likely error over any memoryless quantum channel, while its complexity grows only linearly with the number of encoded qubits.
