论文摘要
与标准量子非局部性相比，网络非局部性表现出完全新颖的量子相关性。已经表明，网络非局部性可以通过弱测量结果在广义的双腹场景中共享[Phys。 Rev. A. 105，042436（2022）]。在本文中，我们通过弱测量值调查了网络非局部性共享，其中具有任意数量的无偏二分法输入$ k $的通用星形网络配置，其中包括$ n $分支，并在每个分支中增加（$ m $ -1）在每个分支的派对中，在原始星网络$（n，m = 1，m = 1，k = 2）$场景中。结果表明，所有观察者之间的网络非局部性共享可以从同时违反$ 2^n $不平等的违反（$ n，m = 2，k = 2 $）和（$ n，m = 2，k = 3 $）方案中的任何$ n $分支。还分析了通过精确的噪声模型的网络非定位共享的噪声阻力。
Network nonlocality exhibits completely novel quantum correlations compared to standard quantum nonlocality. It has been shown that network nonlocality can be shared in a generalized bilocal scenario via weak measurements [Phys. Rev. A. 105, 042436 (2022)]. In this paper, we investigate network nonlocality sharing via weak measurements in a generalized star-shaped network configuration with arbitrary numbers of unbiased dichotomic input $k$, which includes $n$ branches and adds ($m$-1) more parties in each branch to the original star network $(n, m=1, k=2)$ scenario. It is shown that network nonlocality sharing among all observers can be revealed from simultaneous violation of $2^n$ inequalities in the ($n, m=2, k=2$) and ($n, m=2, k=3$) scenarios for any $n$ branches. The noise resistance of network nonlocality sharing with a precise noise model is also analyzed.
