Field-induced entanglement in spatially superposed objects

研究成果: Contribution to journalArticle査読

抄録

We discuss the generation of field-induced entanglement between two objects, each in a superposition of two trajectories. The objects have currents coupled to local quantum fields, and the currents are evaluated around each trajectory of the objects. The fields have only dynamical degrees of freedom and satisfy the microcausality condition. We find that the superposed state of trajectories cannot be entangled when the objects are spacelike separated. This means that the quantum fields do not generate spacelike entanglement in the superposition of two trajectories of each object.
