基于Hermitian曲线的嵌套码偶

On nested code pairs from the Hermitian curve

René Bødker Christensen, Olav Geil

摘要:

嵌套码对在ramp秘密共享方案的构造[Kurihara et al. 2012]和量子码的CSS构造[Ketkar et al. 2006]中起着至关重要的作用。重要的参数是(1)余维数,(2)码的相对最小距离,和(3)对偶码集的相对最小距离。给定其中两个的值,一个目标是找到一组嵌套代码,其参数具有这些值,并且剩余的参数尽可能大。在这项工作中,我们研究了嵌套的代码从厄米曲线。对于不太小的余维,我们提出了改进的结构,并提供封闭的公式估计其性能。对于小余维,我们展示了如何选择一点代数几何码对,以这样一种方式,其中一个相对最小距离大于相应的非相对最小距离。

英文摘要:

Nested code pairs play a crucial role in the construction of ramp secret sharing schemes [Kurihara et al. 2012] and in the CSS construction of quantum codes [Ketkar et al. 2006]. The important parameters are (1) the codimension, (2) the relative minimum distance of the codes, and (3) the relative minimum distance of the dual set of codes. Given values for two of them, one aims at finding a set of nested codes having parameters with these values and with the remaining parameter being as large as possible. In this work we study nested codes from the Hermitian curve. For not too small codimension, we present improved constructions and provide closed formula estimates on their performance. For small codimension we show how to choose pairs of one-point algebraic geometric codes in such a way that one of the relative minimum distances is larger than the corresponding non-relative minimum distance.
