摘要

我们提出了高能物理中通用截面量子积分的通用构件。我们利用在quantum的量子MCI引擎中实现的傅立叶量子蒙特卡罗积分（MCI）来提供一种可扩展的方法，用于生成可以实现通用横截面计算的有效电路，提供相对于经典MCI的均方根误差收敛的二次加速。我们着重于衰变过程的一个具体例子来说明我们的工作。

A general approach to quantum integration of cross sections in high-energy physics

We present universal building blocks for the quantum integration of generic cross sections in high-energy physics. We make use of Fourier quantum Monte Carlo integration (MCI) as implemented in Quantinuum’s Quantum MCI engine to provide an extendable methodology for generating efficient circuits that can implement generic cross-section calculations, providing a quadratic speed-up in root mean-squared error convergence with respect to classical MCI. We focus on a concrete example of a decay process to illustrate our work.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
