Non-technical Abstract: Quantum entanglement is a fascinating phenomenon whereby quantum particles can be separated by great distances and demonstrate correlations that go beyond what is possible with classical physics. Entanglement holds great promise to revolutionize communication in network settings where multiple separated users will someday possess and share entangled quantum particles: the "quantum internet" of the future. The objective of this project is to harness a novel experimental platform being built in Boulder, Colorado to demonstrate entangled effects such as entangled measurements and multi-party entangled states. Through a partnership with the University of New Orleans, this work will serve as a training platform to build expertise among undergraduate and graduate students, providing a critical boost to the emergence of a quantum-trained workforce capable of tackling the problems of tomorrow. Technical Abstract: This project’s approach to quantum networking is based on heralded path-entangled photonic states. Heralded entangled states generated by multiple parties can be used to create genuine multipartite entanglement through appropriate measurements and operations at a central node. Heralding avoids post-selection analysis, which becomes necessary when attempting to witness multipartite entanglement by interfering multiple sources that generate entangled particle pairs only probabilistically, such as in spontaneous parametric down-conversion. The heralded setup is thus well suited for the central scientific problem of this project: to definitively demonstrate, with minimal auxiliary assumptions, multi-party entangled effects that go beyond two-party entanglement alone, such as entangled measurements and multi-party entangled states. This project supports research on how to best measure and characterize the resulting multipartite correlations, and how to perform careful statistical analysis to test constraints whose violation indicate the presence of more sophisticated entangled states and measurements, extending methods that were developed for first generation of 2-party Bell experiments.This project is jointly funded by The Office of Multidisciplinary Activities (MPS/OMA), the Established Program to Stimulate Competitive Research (EPSCoR), and Technology Frontiers Program (TIP/TF).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要：量子纠缠是一种引人入胜的现象，可以通过大距离将量子颗粒分开，并证明相关性超出了与经典物理学的可能性。 《纠缠》具有巨大的希望，可以彻底改变网络设置中的沟通，其中有一天将拥有并共享纠缠量子粒子：未来的“量子互联网”。该项目的目的是利用科罗拉多州博尔德市建造的新型实验平台，以展示纠缠效果，例如纠缠的测量和多方纠缠状态。通过与新奥尔良大学建立合作伙伴关系，这项工作将成为一个培训平台，以在本科生和研究生中建立专业知识，从而极大地推动了量子训练的劳动力的出现，能够解决明天的问题。技术摘要：该项目的量子网络方法基于预示的路径输入光子状态。由多方产生的宣传纠缠状态可用于通过中央节点的适当测量和操作来创建真正的多部分纠缠。预示避免了选择后分析，这是试图通过干扰多种来源来见证多方纠缠的必要条件。因此，预示的设置非常适合该项目的中心科学问题：确定证明，具有最小的辅助假设，多方纠缠的效果超出了两党的纠缠，例如纠结的测量和多方纠缠的状态。该项目支持有关如何最好地衡量和表征所得的多方相关性的研究，以及如何进行仔细的统计分析以测试违规的约束，其违规表明存在更复杂的纠缠状态和测量，扩展了为第一代铃铛实验开发的方法，这些方法是由两部分钟声实验的竞争计划（MIDIdioldiaral Active of MutiDipary Active（MMS/Oma）共同资助的， （EPSCOR）和技术边界计划（TIP/TF）。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估诚实的支持。
