首先利用有限几何的特点构造经典低密度奇偶校验(LDPC)矩阵,然后通过对校验矩阵的行或列变换构造其对偶码,本文提出了一种以量子CSS码为理论基础的基于有限几何的量子LDPC码。并对其进行了充分的理论推导,从而使用有限几何构造量子LDPC码称为一种可行的途径。 First of all, we construct a classical low density parity check (LDPC) matrix by using finite geometric features, and then construct its dual code by row or column transformation of the check matrix. In this paper, we propose a quantum geometry based on finite geometry Quantum LDPC code. And has carried on the sufficient theory deduction to it, thus uses the finite geometry to construct the quantum LDPC yard to be called a feasible way.
