论文摘要
我们使用超级键入来实验实现基于量子优雅的关节测量的确定性纠缠交换。这些是两个量子位的联合投影，这些量子位于高度对称的，ISO的底座上。我们报告的测量保真度不到$ 97.4 \％$。我们通过使用纠缠交换程序来展示这些测量结果的应用，以证明对射骨铃铛不平等的原则违规形式的量子相关性，以及与完全网络非局部性相对应的更为严格的相关标准。我们的结果是对范式铃铛状态测量以外的纠缠测量和非局部性的尝试，它们显示了更一般的测量在纠缠交换方案中的相关性。
We use hyper-entanglement to experimentally realize deterministic entanglement swapping based on quantum Elegant Joint Measurements. These are joint projections of two qubits onto highly symmetric, iso-entangled, bases. We report measurement fidelities no smaller than $97.4\%$. We showcase the applications of these measurements by using the entanglement swapping procedure to demonstrate quantum correlations in the form of proof-of-principle violations of both bilocal Bell inequalities and more stringent correlation criteria corresponding to full network nonlocality. Our results are a foray into entangled measurements and nonlocality beyond the paradigmatic Bell state measurement and they show the relevance of more general measurements in entanglement swapping scenarios.
