空间叠加物体中的场致纠缠

Field-induced entanglement in spatially superposed objects

Akira Matsumura

摘要:

本文讨论了两个轨道叠加的两个物体之间的场诱导纠缠的产生,物体具有与局域量子场耦合的电流,电流在物体的每个轨道周围进行计算,场只有动力学自由度,满足微因果性条件.我们发现,当两个物体是类空分离的时,轨道的叠加态不能纠缠,这意味着在每个物体的两个轨道的叠加中,量子场不产生类空纠缠。

英文摘要:

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.
