拓扑码通用神经网络解码的优势

Advantages of versatile neural-network decoding for topological codes

Nishad Maskara, Aleksander Kubica, Tomas Jochym-O'Connor

摘要:

即使对于简单的噪声模型,找到通用稳定器代码中的错误的最佳校正也是计算上困难的问题。虽然这个任务可以简化为一些结构的代码,如拓扑稳定器代码,开发良好和有效的解码器仍然是一个挑战。在我们的工作中,我们系统地研究了一类非常通用的基于前馈神经网络的解码器。为了证明适应性,我们将神经解码器应用于具有现实特征(如空间相关误差)的各种噪声模型下的三角色和复曲面代码。我们报告说,神经解码器提供了显着的改善领先的高效解码器的纠错阈值。使用神经网络简化了设计性能良好的解码器的过程,并且不需要底层噪声模型的先验知识。

英文摘要:

Finding optimal correction of errors in generic stabilizer codes is a computationally hard problem, even for simple noise models. While this task can be simplified for codes with some structure, such as topological stabilizer codes, developing good and efficient decoders still remains a challenge. In our work, we systematically study a very versatile class of decoders based on feedforward neural networks. To demonstrate adaptability, we apply neural decoders to the triangular color and toric codes under various noise models with realistic features, such as spatially-correlated errors. We report that neural decoders provide significant improvement over leading efficient decoders in terms of the error-correction threshold. Using neural networks simplifies the process of designing well-performing decoders, and does not require prior knowledge of the underlying noise model.
