论文摘要
高质量的模拟数据对于粒子物理发现至关重要。因此，Parton淋浴算法是事件生成器程序中数据综合的主要构建基础。但是，自1980年代以来，用于产生Parton阵雨的核心算法几乎没有改变。随着量子计算机的快速和持续开发，需要专门的算法来利用量子计算机提供的潜力来解决高能物理学中的问题。本文提出了一种使用离散QCD方法合成Parton阵雨的新方法。该算法受益于优雅的量子步行实现，该实现可以嵌入古典工具链中。我们使用IBM_ALGIERS设备对Parton淋浴配置进行采样，并生成与Aleph，Delphi和Opal实验进行的测量相比的数据。这是第一次使用嘈杂的中间量子量子（NISQ）设备来模拟现实的高能粒子碰撞事件。
High-quality simulated data is crucial for particle physics discoveries. Therefore, parton shower algorithms are a major building block of the data synthesis in event generator programs. However, the core algorithms used to generate parton showers have barely changed since the 1980s. With quantum computers' rapid and continuous development, dedicated algorithms are required to exploit the potential that quantum computers provide to address problems in high-energy physics. This paper presents a novel approach to synthesising parton showers using the Discrete QCD method. The algorithm benefits from an elegant quantum walk implementation which can be embedded into the classical toolchain. We use the ibm_algiers device to sample parton shower configurations and generate data that we compare against measurements taken at the ALEPH, DELPHI and OPAL experiments. This is the first time a Noisy Intermediate-Scale Quantum (NISQ) device has been used to simulate realistic high-energy particle collision events.
