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…
Reweighted Mixup for Subpopulation Shift
Zongbo Han, Zhipeng Liang, Fan Yang +8
Subpopulation shift exists widely in many real-world applications, which refers to the training and test distributions that contain the same subpopulation groups but with different…
Improved Polar-code-based Efficient Post-processing Algorithm for Quantum Key Distribution
Junbing Fang, Zhengzhong Yi, Jin Li +5
Combined with one-time pad encryption scheme, quantum key distribution guarantees the unconditional security of communication in theory. However, error correction and privacy ampli…
