摘要
量子模拟有望通过精确模拟复杂物质态、其微观激发和宏观响应函数来加速材料发现。解析潜在相互作用动力学的核心挑战在于将高保真度演化与操纵量子多体态中单个准粒子所需的复杂控制相结合。在这里，我们报告了使用多达97个量子比特的模数超导处理器对二维XY自旋-1/2磁体中的线性和非线性响应函数进行的高精度模拟。通过将数字门与通过哈密顿学习精确表征的模拟演化交错进行，我们选择性地在可调能量密度下激发磁振子。首先测量线性磁振子响应——中子散射实验中的核心探针——我们提取了温度相关的谱和寿命。我们的结果揭示了磁振子衰变率在布里渊区内的显著变化，在范霍夫奇点附近增强，而边缘局域模式则受到抑制。接下来，我们进行了一系列非线性测量，包括研究自散射机制，以及泵浦-探测光谱以直接表征磁振子相互作用。虽然矩阵乘积态模拟在小系统或低温下能很好地捕捉动力学，但它们的预测在远离这些极限时会变得不准确。这项工作展示了量子磁体中相互作用动力学的精确模拟，并为准粒子及其微观散射机制提供了关键见解。
