Non-technical Description:This project creates a general-purpose, open-access, and programmable quantum network prototype for the quantum information science and engineering (QISE) community to experiment new quantum technologies and train teachers and students of all majors. The developed new knowledge and prototype have the potential to reduce financial costs through software-based rather than hardware-based solutions, support broad and replicable quantum research and education, build an agile, flexible, and scalable quantum network infrastructure for open and equitable access, and help the U.S. out-compete global competitors in QISE. Moreover, the developed prototype is ideal for QISE training and education through its easy access by teachers and students without requiring their prior knowledge of operating complex quantum hardware. A new curriculum based on this prototype will be further created and disseminated through existing partnership programs to train a large body of college students.Technical Description:Existing quantum network systems are mostly local, small-scale, and application-specific, reminiscent of the era of the internet onset. The future expansion of quantum networks, without thoughtful planning, would inevitably lead to the same pitfalls as the classical internet like network ossification. In this project, the key applied methodology is virtualization that permits rapid and flexible experimentation of new quantum technologies via agile software controls, without resorting to daunting hardware modifications. To this end, the research team initiates a comprehensive research agenda consisting of three thrusts: (1) the team identifies and re-designs key quantum components, e.g., entangled photon sources and detectors, based on which a software architecture is further developed for the proposed virtual quantum network (VQN) prototype. The goal of this thrust is to lay the foundation and create the “skeleton” for the VQN prototype. (2) The team then develops a suite of protocols to improve the efficiency of the VQN prototype. It includes virtual slice placement and traffic routing for network load balance; queuing users' requests for aggregated service and increased network capacity; and network event, e.g., entanglement purification and swapping, scheduling, and control for high-quality virtual services. This thrust’s goal is to functionalize and create the “flesh and blood” of the VQN prototype. (3) The VQN prototype is implemented in a quantum-network testbed and evaluated against several figures of merit. Moreover, two Application Programming Interface (API) interfaces are developed to allow nationwide universities to use this platform for replicable research and educational activities. The goal of this thrust is to perform a quantitative assessment on the VQN prototype and create an open and education-friendly platform for the broad QISE community.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.

非技术描述：该项目为量子信息科学与工程（QISE）社区（QISE）社区创建了通用，开放式和可编程量子网络原型，以实验新的量子技术，并培训所有专业的教师和学生。开发的新知识和原型具有通过基于软件的而不是基于硬件的解决方案来降低财务成本的潜力，支持广泛而可复制的量子研究和教育，建立敏捷，灵活且可扩展的量子网络基础架构，以开放和公平访问，并帮助美国在Qise中竞争全球竞争者。此外，开发的原型非常适合通过教师和学生轻松访问QISE培训和教育，而无需先前了解操作复杂的量子硬件。将通过现有合作伙伴计划培训大量大学生的新课程将进一步创建和传播。技术描述：现有的量子网络系统大多是本地，小规模且特定于应用程序的，让人联想到互联网发作时代。未来的量子网络的扩展在没有周到的计划的情况下，不可避免地会导致与古典互联网（如网络骨化）相同的陷阱。在该项目中，关键应用方法是虚拟化，该虚拟化允许通过敏捷软件控制对新的量子技术进行快速而灵活的实验，而无需诉诸于彻底的硬件修改。为此，研究团队启动了由三个推力组成的全面研究议程：（1）团队识别并重新设计了关键的量子组件，例如纠缠的光子源和检测器，基于该软件架构，该软件架构是为所提出的拟议的虚拟量子网络（VQN）原型开发的。这种推力的目的是为VQN原型奠定基础并为“骨架”创建“骨架”。 （2）团队随后开发了一套协议，以提高VQN原型的效率。它包括用于网络负载余额的虚拟切片放置和流量路由；排队用户的汇总服务请求和增加网络容量；和网络事件，例如，纠缠净化和交换，调度和控制高质量虚拟服务。这个推力的目标是使VQN原型的功能化并创建“血液和血液”。 （3）VQN原型在量子网络测试床上实现，并针对几个功绩数字进行了评估。此外，开发了两个应用程序编程界面（API）接口，以允许全国大学使用此平台进行可复制的研究和教育活动。这一目标的目的是在VQN原型上进行定量评估，并为广泛的Qise社区创建一个开放且教育的平台。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标准来评估NSF的法定任务。
