探测器可观测量因其固有的实时性和渐近性，对非微扰格点方法构成了根本性挑战。我们提出量子模拟平台作为研究这些可观测量的理想环境。以量子自旋系统作为演示，我们构建了格点探测器算子，并建立了它们与连续能量流可观测量之间的联系。我们在$1+1$维量子伊辛模型中演示了这一框架，其中有限格点计算在临界点处与共形场论预期定量一致。这些结果支持将格点流算子解释为在标度和渐近极限下连续探测器的正则化对应物，为在桌面级量子平台上实现高能对撞机物理提供了一条具体途径。
英文摘要
Detector observables pose a fundamental challenge for nonperturbative lattice methods due to their intrinsically real-time and asymptotic nature. We propose quantum simulation platforms as an ideal setting for studying these observables. Using quantum spin systems as a demonstration, we construct lattice detector operators and establish their connection to continuum energy-flow observables. We demonstrate this framework in the $1+1$-dimensional quantum Ising model, where finite lattice calculations show quantitative agreement with conformal field theory expectations at criticality. These results support the interpretation of the lattice flow operators as regulated counterparts of continuum detectors in the scaling and asymptotic limits, providing a concrete route toward realizing high-energy collider physics on table-top quantum platforms.
