论文摘要
我们提出了在高能物理学(HEP)的背景下,首次尝试通过估计Parton分布函数(PDFS)来设计量子电路,以确定质子的Parton含量(PDFS)。对量子计算的兴趣日益增长,以及新算法和量子硬件设备的最新发展激发了对应用于HEP的方法的研究。在这项工作中,我们确定了适用于PDFS表示(QPDF)的变异量子电路的架构。我们展示了有关当前的实验局限性,展示了有关QPDF在实际量子设备上部署的实验。最后,我们使用量子计算机模拟在经典硬件上从对撞机数据中执行全局QPDF测定,并比较获得的Partons和相关的现象学预测,涉及HADRONIC过程与现代PDF。
We present a first attempt to design a quantum circuit for the determination of the parton content of the proton through the estimation of parton distribution functions (PDFs), in the context of high energy physics (HEP). The growing interest in quantum computing and the recent developments of new algorithms and quantum hardware devices motivates the study of methodologies applied to HEP. In this work we identify architectures of variational quantum circuits suitable for PDFs representation (qPDFs). We show experiments about the deployment of qPDFs on real quantum devices, taking into consideration current experimental limitations. Finally, we perform a global qPDF determination from collider data using quantum computer simulation on classical hardware and we compare the obtained partons and related phenomenological predictions involving hadronic processes to modern PDFs.
