量子神经网络克服幅度编码限制

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-02 05:00

研究人员发现量子神经网络（QNNs）的幅度编码存在表示限制，即无法区分相差非零实数缩放的输入。这种源于归一化的不变性限制了QNNs的假设类别。该研究提出了一种固定的非线性特征映射，克服了这一瓶颈，在保持对数量子比特缩放的同时，能够区分所有实数输入。在分类基准测试中，使用这种新编码的QNNs与传统的幅度和角度编码方法相比，分类准确率提高了21-44%。 AI

影响这项研究有望增强量子神经网络在复杂数据分析和分类任务中的能力。

Overcoming the Representational Limitations of Amplitude Encoding for Quantum Neural Networks

arXiv:2610.41824v1 Announce Type: cross Abstract: Quantum Neural Networks (QNNs) offer a framework for learning functions from classical data, but their expressive power depends critically on how inputs are encoded into quantum states. Angle encoding can require resources that sc…
