This Distributed Quantum Information Project will explore quantum architectures that allow for distributed quantum resources, i.e. a network of quantum nodes connected with quantum channels. The project centers on the realization of a Matter-light interconnect with Cavity QED where neutral atoms and ensembles of atoms will provide the quantum nodes and qubits while the quantum channel will be done by optical means or a quantum bus of coherently transported atoms. This quantum network architecture will allow the generation of entanglement between atoms and photons, and entanglement between distant nodes, a critical part of the interface necessary for quantum computing . Investigations of quantum coherence and entanglement over macroscopic distances will also enhance our understanding of the sources of decoherence and their effects on the fidelity of the transmitted information, and the effects of quantum measurement, quantum feedback, and back-action. The prototype quantum bus will include quantum control in its operation, an innovative approach in quantum computing (dmc). This research effort is a collaboration between experimentalists and theorists, and between academic and government scientists. Graduate students and post-doctoral associates will be trained in quantum information science through the establishment of information science pre- and post-doctoral fellowships. The proposed in-house rotation and world-wide scientist exchange program will not only give Fellows exposure to all aspects of the field and valuable interaction with world leaders, it will also ensure a constant infusion of new ideas. Special forums for undergraduate students will be held in the evenings during the academic year and research projects will be arranged for them in the summer. Participating students will be recruited not only from existing programs, but from the rich source of Historically Black Colleges and Universities in Maryland, Washington, DC and Virginia. A dynamic web page, an active seminar series and an annual open house will be key channels through which we will disseminate our findings to both the scientific and non-technical communities.Funding for this project is provided by the Division of Physics in the Mathematical and Physical Sciences Directorate and by the Division of Computing and Communication Foundations in the Directorate for Computer and Information Science and Engineering.

这个分布式量子信息项目将探索允许分布式量子资源的量子架构，即与量子信道连接的量子节点网络。该项目的中心是实现与腔QED的物质-光互连，其中中性原子和原子系综将提供量子节点和量子位，而量子通道将通过光学手段或相干传输原子的量子总线完成。这种量子网络架构将允许在原子和光子之间产生纠缠，以及在遥远的节点之间产生纠缠，这是量子计算所必需的接口的关键部分。对宏观距离上的量子相干和纠缠的研究也将增强我们对退相干的来源及其对传输信息保真度的影响，以及量子测量、量子反馈和反作用的影响的理解。量子总线的原型将在其运行中包括量子控制，这是量子计算（dmc）的一种创新方法。这项研究工作是实验学家和理论家之间，以及学术和政府科学家之间的合作。研究生和博士后助理将通过建立信息科学博士前和博士后奖学金进行量子信息科学培训。拟议的内部轮换和世界范围的科学家交流计划不仅将使研究员接触到该领域的各个方面，并与世界领导人进行有价值的互动，还将确保不断注入新的想法。本科生的特别论坛将在学年的晚上举行，并在夏季为他们安排研究项目。参与的学生不仅将从现有的项目中招募，而且将从马里兰州、华盛顿、华盛顿特区和弗吉尼亚州历史上黑人学院和大学的丰富来源中招募。一个动态的网页，一个活跃的系列研讨会和一个年度开放日将是我们将通过它向科学和非技术社区传播我们的研究结果的主要渠道。该项目的资金由数学和物理科学局物理司和计算机和信息科学与工程局计算和通信基础司提供。
