拓扑二维稳定子码的最优资源比较研究

Optimal Resources for Topological 2D Stabilizer Codes: Comparative Study

H. Bombin, M. A. Martin-Delgado

摘要:

我们研究所需的资源,以构建拓扑二维稳定器代码的一种方式来估计其效率的一部分,这使我们进行比较研究的表面码和颜色代码。本研究阐明了这两种类型的稳定器代码之间的相似性和差异。我们计算了表面码$C_s$和颜色码$C_c$在几种情况下的纠错率$C:=n/d^2$。在环面上,典型值为$C_s=2$和$C_c=3/2$,但我们发现最佳值为$C_s=1$和$C_c=9/8$。对于平面码,一个典型的值是$C_s=2$,而我们发现,最佳值是$C_s=1$和$C_c=3/4$。一般来说,颜色码编码的逻辑量子比特是表面码的两倍。

英文摘要:

We study the resources needed to construct topological 2D stabilizer codes as a way to estimate in part their efficiency and this leads us to perform a comparative study of surface codes and color codes. This study clarifies the similarities and differences between these two types of stabilizer codes. We compute the error correcting rate $C:=n/d^2$ for surface codes $C_s$ and color codes $C_c$ in several instances. On the torus, typical values are $C_s=2$ and $C_c=3/2$, but we find that the optimal values are $C_s=1$ and $C_c=9/8$. For planar codes, a typical value is $C_s=2$, while we find that the optimal values are $C_s=1$ and $C_c=3/4$. In general, a color code encodes twice as much logical qubits as a surface code does.
