Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy laboratory setups. The feasibility of these studies in the high-energy regime explored by particle colliders was only recently shown and has gathered the attention of the scientific community. For the range of particles and fundamental interactions involved, particle colliders provide a novel environment where quantum information theory can be probed, with energies exceeding by about 12 orders of magnitude those employed in dedicated laboratory setups. Furthermore, collider detectors have inherent advantages in performing certain quantum information measurements and allow for the reconstruction of the state of the system under consideration via quantum state tomography. Here, we elaborate on the potential, challenges, and goals of this innovative and rapidly evolving line of research and discuss its expected impact on both quantum information theory and high-energy physics.
量子力学的一些最令人惊讶和显著的特性，比如纠缠和贝尔非定域性，仅在专门的低能实验室装置中得到了广泛研究。粒子对撞机所探索的高能 regime 中进行这些研究的可行性直到最近才被证明，并且已经引起了科学界的关注。对于所涉及的粒子范围和基本相互作用而言，粒子对撞机提供了一个全新的环境，在这个环境中量子信息理论能够得到探究，其能量比专门实验室装置中所使用的能量高出大约 12 个数量级。此外，对撞机探测器在执行某些量子信息测量方面具有内在优势，并且能够通过量子态层析成像重建所考虑系统的状态。在此，我们详细阐述这一创新且快速发展的研究方向的潜力、挑战和目标，并讨论其对量子信息理论和高能物理的预期影响。
