阿贝尔和非阿贝尔任意子的主动纠错

Active error correction for Abelian and non-Abelian anyons

James R. Wootton, Adrian Hutter

摘要:

我们考虑一类解码算法,适用于阿贝尔和非阿贝尔任意子的纠错。这个类包括最近引起关注的多个算法,包括Bravyi-Haah RG解码器。它们被应用到两个问题的Single Shot错误校正(完美的综合征测量)和主动错误校正(嘈杂的综合征测量)。对于阿贝尔模型,我们提供了一个阈值证明在这两种情况下,显示有一个有限的噪声阈值下,错误可以任意抑制时,在这个类中的任何解码器被使用。对于非阿贝尔模型,这样的证明被发现为Single Shot的情况。本文详细研究了非阿贝尔任意子主动纠错译码的方法。与阿贝尔的情况下的差异进行了讨论。

英文摘要:

We consider a class of decoding algorithms that are applicable to error correction for both Abelian and non-Abelian anyons. This class includes multiple algorithms that have recently attracted attention, including the Bravyi-Haah RG decoder. They are applied to both the problem of single shot error correction (with perfect syndrome measurements) and that of active error correction (with noisy syndrome measurements). For Abelian models we provide a threshold proof in both cases, showing that there is a finite noise threshold under which errors can be arbitrarily suppressed when any decoder in this class is used. For non-Abelian models such a proof is found for the single shot case. The means by which decoding may be performed for active error correction of non-Abelian anyons is studied in detail. Differences with the Abelian case are discussed.
