摘要:

本工作引入了一种通过分段多项式特征将连续变量嵌入量子电路的新方法,并利用低秩张量网络实现。我们的方法称为分段多项式张量网络量子特征编码(PPTNQFE),旨在通过引入空间局部化表示来拓宽量子算法的适用范围,使其适用于偏微分方程和函数回归等数值应用。我们通过对离散化微分方程解的高效点求值,以及对具有跳跃间断等局部特征的函数进行建模,展示了 PPTNQFE 的潜力。尽管前景可观,但仍存在未探索的噪声影响和可训练电路设计等挑战。本研究为通过新型特征嵌入增强量子模型,以及在量子机器学习中利用张量网络表示处理更广泛的函数类型开辟了新途径。

英文摘要:

This work introduces a novel method for embedding continuous variables into quantum circuits via piecewise polynomial features, utilizing low-rank tensor networks. Our approach, termed Piecewise Polynomial Tensor Network Quantum Feature Encoding (PPTNQFE), aims to broaden the applicability of quantum algorithms by incorporating spatially localized representations suited for numerical applications like partial differential equations and function regression. We demonstrate the potential of PPTNQFE through efficient point evaluations of solutions of discretized differential equations and in modeling functions with localized features such as jump discontinuities. While promising, challenges such as unexplored noise impact and design of trainable circuits remain. This study opens new avenues for enhancing quantum models with novel feature embeddings and leveraging TN representations for a wider array of function types in quantum machine learning.
