标题： Entanglement structure of quantum fields through local probes

摘要： 我们提出一个框架，用于研究受相对论量子信息形式主义中粒子探测器启发的量子场理论的纠缠结构。 该框架原则上可以用于忠实地捕捉时空任意形状区域之间的量子场理论中的纠缠，而不会遇到紫外发散问题，从而绕过其他方法中通常存在的许多问题。 我们的结果还确立了纠缠获取效率的极限，并可能用于在场论中激发对时空子区域之间纠缠的操作定义。 显示英文摘要

摘要： We present a framework to study the entanglement structure of a quantum field theory inspired by the formalism of particle detectors in relativistic quantum information. This framework can in principle be used to faithfully capture entanglement in a QFT between arbitrary-shaped regions of spacetime without encountering UV divergences, bypassing many of the issues typically present in other approaches. Our results also establish the limits of the efficiency of entanglement harvesting, and may also be used to motivate an operational definition of entanglement between spacetime subregions in field theory.
