二维拓扑稳定子码的结构

Structure of 2D Topological Stabilizer Codes

H. Bombin

摘要:

我们提供了一个详细的研究二维拓扑稳定量子纠错码的一般结构,包括子系统代码。在平移不变性的唯一假设下,我们证明了所有这些代码都可以理解为带有一定拓扑电荷的弦算子的同源性。在子空间码的情况下,我们证明了两个码在一组适当的局部变换下是等价的当且仅当它们具有等价的拓扑荷。我们的方法强调局部性质的代码在全球的。

英文摘要:

We provide a detailed study of the general structure of two-dimensional topological stabilizer quantum error correcting codes, including subsystem codes. Under the sole assumption of translational invariance, we show that all such codes can be understood in terms of the homology of string operators that carry a certain topological charge. In the case of subspace codes, we prove that two codes are equivalent under a suitable set of local transformations if and only they have equivalent topological charges. Our approach emphasizes local properties of the codes over global ones.
