叶状量子码

Foliated Quantum Codes

A. Bolt, G. Duclos-Cianci, D. Poulin, T. M. Stace

摘要:

我们展示了如何从高度纠缠的团簇态构造一大类量子纠错码,称为CSS码。这成为将一系列这样的簇状态分成更大的簇状态的协议中的原语,实现了分层的量子纠错。我们用几种常见的量子纠错码构造了这种结构,并提出了一种通用的解码方法。我们数值评估的纠错性能的一个家庭的有限速率CSS码称为涡轮码,发现它表现良好,超过中等深度的叶状。叶码在量子中继器和基于容错测量的量子计算中有应用。

英文摘要:

We show how to construct a large class of quantum error correcting codes, known as CSS codes, from highly entangled cluster states. This becomes a primitive in a protocol that foliates a series of such cluster states into a much larger cluster state, implementing foliated quantum error correction. We exemplify this construction with several familiar quantum error correction codes, and propose a generic method for decoding foliated codes. We numerically evaluate the error-correction performance of a family of finite-rate CSS codes known as turbo codes, finding that it performs well over moderate depth foliations. Foliated codes have applications for quantum repeaters and fault-tolerant measurement-based quantum computation.
