Hypergraph product code with 0.2 constant coding rate and high code capacity noise threshold
Zhengzhong Yi, Zhipeng Liang, Jiahan Chen +2
The low coding rate of quantum stabilizer codes results in formidable physical qubit overhead when realizing quantum error correcting in engineering. In this letter, we propose a n…

Determining the upper bound of code distance of quantum stabilizer codes through Monte Carlo method based on fully decoupled belief propagation
Zhipeng Liang, Zicheng Wang, Zhengzhong Yi +3
Code distance is an important parameter for quantum stabilizer codes (QSCs). Directly precisely computing it is an NP-complete problem. However, the upper bound of code distance ca…

Recursive expansion of Tanner graph: a method to construct stabilizer codes with high coding rate
Zhengzhong Yi, Zhipeng Liang, Zicheng Wang +4
Quantum stabilizer codes face the problem of low coding rate. In this article, following the idea of recursively expanding Tanner graph proposed in our previous work, we try to con…
