具有实际物理约束的量子码的拓扑方法

Topological approach toward quantum codes with realistic physical constraints

Beni Yoshida

摘要:

本文分析并部分回答了以下有关量子码在实际物理约束下编码性能的基本限制的公开问题:(a)具有几何局域生成元的量子纠错码的码距上界;(b)自纠错量子存储器的可行性。为了研究这些问题,我们研究了稳定剂代码支持本地相互作用项的平移和规模对称的$D$维晶格。我们的分析使用拓扑的概念出现在几何形状的逻辑运算符,这揭示了一个令人惊讶的新的光量子编码理论的物理约束。

英文摘要:

The following open problems, which concern a fundamental limit on coding properties of quantum codes with realistic physical constraints, are analyzed and partially answered here: (a) the upper bound on code distances of quantum error-correcting codes with geometrically local generators, (b) the feasibility of a self-correcting quantum memory. To investigate these problems, we study stabilizer codes supported by local interaction terms with translation and scale symmetries on a $D$-dimensional lattice. Our analysis uses the notion of topology emerging in geometric shapes of logical operators, which sheds a surprising new light on theory of quantum codes with physical constraints.
