标题： Simulations of Subatomic Many-Body Physics on a Quantum Frequency Processor

摘要： 模拟复杂的多体量子现象是推动量子计算发展的主要科学动力之一，人们正在探索各种技术来应对这类系统。 我们展示了迄今为止基于光子的最大规模的模拟结果，并将其应用于亚原子物理学领域。 利用全光量子频率处理器，我们计算了包括氚（$^3$H）、$^{3}$He和alpha粒子（$^{4}$He）在内的轻核基态能量。 补充这些计算，并使用一个68维的希尔伯特空间，我们的光子模拟器被用于施温格模型中重介子间的两体和三体力的亚核计算。 这项工作是在量子频率处理器上模拟亚原子多体物理的第一步——增强从夸克到原子核尺度的经典计算。 显示英文摘要

摘要： Simulating complex many-body quantum phenomena is a major scientific impetus behind the development of quantum computing, and a range of technologies are being explored to address such systems. We present the results of the largest photonics-based simulation to date, applied in the context of subatomic physics. Using an all-optical quantum frequency processor, the ground-state energies of light nuclei including the triton ($^3$H), $^{3}$He, and the alpha particle ($^{4}$He) are computed. Complementing these calculations and utilizing a 68-dimensional Hilbert space, our photonic simulator is used to perform sub-nucleon calculations of the two-body and three-body forces between heavy mesons in the Schwinger model. This work is a first step in simulating subatomic many-body physics on quantum frequency processors---augmenting classical computations that bridge scales from quarks to nuclei.
