Collaborative Research: FET: Medium: Quantum Localization and Synchronization Networks

对分别由定位方法和同步方法提供的高精度位置和时间信息的需求正在迅速增长。然而，经典的定位和同步方法正在接近它们的极限。利用量子特性有望将这些边界突破经典限制，并提供前所未有的准确性。该项目旨在为量子局部化和同步网络的设计和分析开发理论和实践方法。这些方法包括统计模型和分布式算法，以利用量子现象进行超越经典的局部化和同步。这项研究的更广泛影响包括为未来的量子局部化和同步网络创建一种新的以网络为中心的方法。这一研究中采用的交叉授粉思想和方法将为量子信息科学的研究带来新的视角和新的方向。拟议研究的成果将通过在主要期刊和国际会议上发表、在研讨会和教程中介绍以及纳入教材等方式广泛传播。此外，该项目将培养一支能够设计和设计未来量子网络的工程师队伍。该项目的成功将有助于美国在量子信息科学和技术方面的领导地位。该奖项将探索量子网络中与离散和连续变量量子态相关的独特性质(例如多体纠缠)提供的新机会和新维度。为此，该项目将采用多学科方法(包括统计推理、网络优化和量子信息科学)来(I)确定量子局部化和同步网络的性能限制，以及(Ii)开发利用量子网络的独特属性的策略。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The demand for highly accurate position and time information, provided by localization and synchronization methods, respectively, is growing rapidly. However, classical localization and synchronization methods are approaching their limits. Utilizing quantum properties promises to push these boundaries beyond classical limitations and provide unprecedented accuracy. This project aims to develop theoretical and practical methodologies for the design and analysis of quantum localization and synchronization networks. These methodologies consist of statistical models and distributed algorithms to harness quantum phenomena for beyond-classical localization and synchronization. The broader impact of this research includes the creation of a new network-centric approach for future quantum localization and synchronization networks. Cross-pollinating ideas and methodologies adopted in this research effort will bring new perspectives and initiate new directions in the study of quantum information science. The outcomes of the proposed research will be widely disseminated through publication in premier journals and international conferences, presentation in seminars and tutorials, as well as integration into teaching materials. Furthermore, the project will create a cadre of engineers with the capability to design and engineer future quantum networks. The success of this project will contribute to the leadership of United States in quantum information science and technology.The award will explore new opportunities and dimensions offered by the unique properties (e.g., multipartite entanglement), associated with discrete- and continuous-variable quantum states, inherent in quantum networks. To this end, the project will employ multidisciplinary approaches (including statistical inference, network optimization, and quantum information science) to (i) determine the performance limits of quantum localization and synchronization networks, and (ii) develop strategies for exploiting the unique properties of quantum networks.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.
