本文概述了量子信息技术在高能物理中的应用，以顶夸克为范例研究纠缠并提出量子层析方案，促成最高能量纠缠观测，开创了QI in HEP新领域。
AI 中文摘要
作为入选“科学前沿奖”的工作，我们在ICBS会议论文集中概述了如何将量子信息（QI）领域的技术应用于高能物理（HEP），并包含了一些新的见解。我们聚焦于顶夸克这一范例性案例，它是相对论性量子比特的“果蝇”。我们研究了量子力学最本质的特征之一——纠缠——在LHC等高能对撞机中顶夸克-反顶夸克产生过程中的存在性。我们还分析了我们提出的针对顶夸克-反顶夸克对的量子层析成像协议的实验方案，该方案最终促成了ATLAS和CMS合作组的纠缠观测，这些观测是迄今最高能量的纠缠观测。我们讨论了我们的工作中发展的概念和技术如何有效地催生了HEP中一个已经广阔而丰富的QI研究领域。
英文摘要
As a work selected for the Frontiers of Science Award, we present in the Proceedings of the ICBS an overview of how the techniques from the field of Quantum Information (QI) can be implemented in High-Energy Physics (HEP), including also some novel insights. We focus on the paradigmatic case of the top quark, a drosophila of a relativistic qubit. We study the presence of entanglement, perhaps the most genuine feature of Quantum Mechanics, in top-antitop quark production in high-energy colliders such as the LHC. We also analyze our experimental proposal of a quantum tomography protocol for the top-antitop quark pair, eventually leading to the entanglement observations by the ATLAS and CMS collaborations, which constituted the highest-energy observations of entanglement ever. We discuss how the concepts and techniques developed in our work have effectively spawned an already vast and rich field of QI in HEP.
