AI 中文摘要
相对论运动对量子纠缠的影响通常归因于加速引起的热噪声。本文表明,对于不对称多体状态,纠缠拓扑可能同样重要。在昂鲁-德维特探测器框架下考虑一个三量子比特星型态,比较两种不等价的加速配置,即中心或外围量子比特进行均匀加速。结果表明这些物理上等效的加速导致定性不同的纠缠动力学:外围量子比特加速会诱导单缠结的复苏,而中心量子比特加速时则没有,真正的三方纠缠单调衰减但稳健性明显不同。结果揭示了相对论纠缠退化的拓扑依赖机制,表明多体量子关联的响应由昂鲁热化和加速子系统的结构作用共同决定。这项工作将不对称量子网络确定为控制相对论量子资源的独特平台。
英文摘要
The influence of relativistic motion on quantum entanglement is commonly attributed to acceleration-induced thermal noise. Here we show that, for asymmetric multipartite states, the topology of entanglement can become equally important. Considering a three-qubit Star state in the Unruh-DeWitt detector framework, we compare two inequivalent acceleration configurations in which either the central or a peripheral qubit undergoes uniform acceleration. We demonstrate that these physically equivalent accelerations lead to qualitatively different entanglement dynamics: acceleration of a peripheral qubit induces a revival of one-tangle that is absent when the central qubit accelerates, whereas genuine tripartite entanglement decays monotonically but with markedly different robustness. Our results uncover a topology-dependent mechanism for relativistic entanglement degradation, showing that the response of multipartite quantum correlations is determined jointly by Unruh thermalization and the structural role of the accelerated subsystem. This work identifies asymmetric quantum networks as a distinct platform for controlling relativistic quantum resources.
