AI 中文摘要
我们采用Unruh-DeWitt探测器模型,研究了具有链状和星型拓扑结构的一般n局域网络中网络非局域性的相对论动力学。研究表明,网络非局域性的相对论退化受底层拓扑结构的强烈调控:链状网络在相对论运动下会发生非n局域性的不可逆突然死亡;而星型网络对相对论退相干表现出显著的鲁棒性。最引人注目的是,由三个外围节点构成的最小星型网络,其网络非局域性会随加速度增大呈现出显著的突然死亡-突然重生转变,这种复现行为揭示了Unruh效应的双重作用:它既能抑制也能保护网络非局域性,为加速度对量子网络的相对论效应提供了新视角。对于更大的星型网络(n>3),非n局域关联在整个加速度范围内均持续存在。这些见解为未来相对论量子通信和传感协议的抗加速度架构的结构优化与设计提供了宝贵的概念指导。
英文摘要
We investigate the relativistic dynamics of network nonlocality in general $n$-local networks with chain and star topologies using the Unruh-DeWitt detector model. We show that the relativistic degradation of network nonlocality is strongly governed by the underlying topology. While chain networks suffer an irreversible sudden death of non-$n$-locality under relativistic motion, star networks exhibit remarkable resilience against relativistic decoherence. Most strikingly, a minimal star network with three peripheral nodes exhibits a remarkable sudden death-sudden birth transition of network nonlocality as the acceleration increases. This reentrant behavior reveals a dual role of the Unruh effect: it can both suppress and protect network nonlocality, offering a new perspective on the relativistic effects of acceleration on quantum networks. For larger star networks ($n>3$), non-$n$-local correlations persist over the entire acceleration regime. These insights provide valuable conceptual guidance for the structural optimization and design of acceleration-resilient architectures for future relativistic quantum communication and sensing protocols.
