论文摘要
由连接遥远用户的纠缠颗粒的独立来源组成的网络是一种快速开发的量子技术，并且是基本物理学的越来越有前途的测试床。在这里，我们通过证明完整的网络非局部性来解决其后古典属性的认证。通过伪造至少一个源是经典的任何模型，即使所有其他来源仅受无信号原则的限制，完全网络非局部性超出了网络中的标准非局部性。我们在星形网络中报告了完整网络非局部性的观察，该网络具有三个独立的光子量子量和联合三质量纠缠式测量值的独立来源。我们的结果构成了Bilocal网络以外的完整网络非局部性的首次实验证明。
Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fundamental physics. Here we address the certification of their post-classical properties through demonstrations of full network nonlocality. Full network nonlocality goes beyond standard nonlocality in networks by falsifying any model in which at least one source is classical, even if all the other sources are limited only by the no-signaling principle. We report on the observation of full network nonlocality in a star-shaped network featuring three independent sources of photonic qubits and joint three-qubit entanglement-swapping measurements. Our results constitute the first experimental demonstration of full network nonlocality beyond the bilocal network.
