The field of quantum information science and technology hinges on unique quantum mechanical phenomena such as entanglement to enable unprecedented capabilities for communication, sensing, and computing. Among these technologies, quantum communication is foreseen to create broad near-term impacts as seen in recent quantum testbeds, teleportation, and entanglement distribution experiments. It is also envisaged to underpin future's fully connected quantum computers, quantum sensors, and a global secure communication network. Mainstream quantum communication platforms, however, rely on expensive, unscalable bulk optics components that impede their widespread deployment. While recent work on integrated quantum communication devices opens a new route to the development of compact quantum-communication systems, an integrated quantum photonics platform encompassing multiple, functional modules on a single chip to generate and process large-scale entanglement remains elusive. This collaborative project will develop a room-temperature integrated quantum photonics platform that incorporates quantum communication modules for scalable generation, processing, multicasting, and detection of large-scale multipartite entanglement in a quantum communication network. This project will leverage the nanofabrication and testing expertise at UCLA and the Interdisciplinary Quantum Information Research and Engineering (INQUIRE) testbed at the University of Arizona (UA) to demonstrate the capability of utilizing a highly compact and mass producible integrated platform to generate, multicast, and detect large-scale entanglement in a real-world setting. The outcome of the project will lay the foundation for future's quantum internet comprised of compact devices linked by large-scale multipartite entanglement. This project will educate and train the next-generation workforce for quantum information science and technology. Specifically, undergraduate and graduate students will grasp essential knowledge and expertise of nanophotonics and quantum information science and technology. They will gain hands-on experience while undertaking research in the INQUIRE testbed. This project will also provide opportunities for various industrial partners to be exposed to state-of-the-art tools grown out of nanophotonics and quantum information science and technology.Technical: The team will follow a system-level design approach for the integrated quantum photonics platform. The project will advance knowledge through a new quantum encoding-and-decoding paradigm that will be seamlessly incorporated into a physical architecture to offer intrinsic protection against loss. The physical architecture will consist of programmable quantum sources, processing units, and receivers using the silicon nitride material system that offer dramatic functionalities. Through ��(3 four-wave mixing in microring resonators and Mach-Zehnder interferometers, the silicon nitride chipset section will produce and process quantum signals with high fidelity and low loss. The silicon nitride section will also provide a classical frequency comb to serve as the pump for the microring resonators and phase references for the Mach-Zehnder interferometers. Programming of the quantum sources, processing units, and receivers will be by modulating the classical comb spectral lines in an integrated hybrid silicon section. In our frequency comb cluster system, the quantum signals will be immune to the programming-induced loss and disturbance. The integrated quantum photonics platform will be programmed to support two system-level quantum communication implementations: 1) a high-rate secure communication system based on quantum illumination; and 2) an entanglement multicasting and purification demonstration.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.

量子信息科学与技术领域依赖于独特的量子力学现象，如纠缠，以实现前所未有的通信，传感和计算能力。在这些技术中，量子通信预计将在近期产生广泛的影响，如最近的量子试验台、隐形传态和纠缠分布实验。它还被设想为未来的全连接量子计算机、量子传感器和全球安全通信网络的基础。然而，主流的量子通信平台依赖于昂贵的、不可扩展的大块光学元件，这阻碍了它们的广泛部署。虽然最近在集成量子通信设备上的工作为紧凑量子通信系统的发展开辟了一条新途径，但在单个芯片上包含多个功能模块的集成量子光子学平台仍然难以产生和处理大规模纠缠。该合作项目将开发一个室温集成量子光子学平台，该平台集成了量子通信模块，用于量子通信网络中大规模多方纠缠的可扩展生成、处理、多播和检测。该项目将利用加州大学洛杉矶分校的纳米制造和测试专业知识，以及亚利桑那大学跨学科量子信息研究和工程（INQUIRE）测试平台，展示利用高度紧凑和可批量生产的集成平台在现实世界中生成、多播和检测大规模纠缠的能力。该项目的成果将为未来由大规模多方纠缠连接的紧凑设备组成的量子互联网奠定基础。该项目将教育和培训量子信息科学和技术的下一代劳动力。具体而言，本科生和研究生将掌握纳米光子学和量子信息科学与技术的基本知识和专业知识。他们将获得实践经验，同时在INQUIRE测试平台进行研究。该项目还将为各种工业合作伙伴提供机会，让他们接触到纳米光子学和量子信息科学与技术所产生的最先进的工具。技术：团队将遵循集成量子光子学平台的系统级设计方法。该项目将通过一种新的量子编码和解码范式来推进知识，该范式将无缝地整合到物理架构中，以提供防止损失的内在保护。物理架构将由可编程量子源、处理单元和使用氮化硅材料系统的接收器组成，这些系统提供了显著的功能。通过和# 55349;及# 57164;(3)在微环谐振器和Mach-Zehnder干涉仪中的四波混频，氮化硅芯片组部分将产生和处理高保真低损耗的量子信号。氮化硅部分还将提供一个经典的频率梳，作为微环谐振器的泵浦和马赫-曾德干涉仪的相位参考。量子源、处理单元和接收器的编程将通过调制集成混合硅截面中的经典梳状光谱线来实现。在我们的频率梳簇系统中，量子信号将不受编程引起的损失和干扰。集成量子光子学平台将被编程为支持两个系统级量子通信实现：1)基于量子照明的高速安全通信系统；2)纠缠多播及其净化演示。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
