ITR: (ASE+NHS) - (int+dmc): Distributed Quantum Information

该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，即与量子通道连接的量子节点网络。该项目的重点是通过腔 QED 实现物光互连，其中中性原子和原子集合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来完成。这种量子网络架构将允许原子和光子之间产生纠缠，以及遥远节点之间的纠缠，这是量子计算所需的接口的关键部分。对宏观距离上的量子相干性和纠缠的研究也将增强我们对退相干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。原型量子总线将在其操作中包括量子控制，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、学术界和政府科学家之间的合作。通过设立信息科学博士前和博士后奖学金，研究生和博士后将接受量子信息科学方面的培训。拟议的内部轮换和全球科学家交流计划不仅能让研究员接触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想法。学年晚上将为本科生举办专题论坛，并在夏季为本科生安排研究项目。参与的学生不仅会从现有项目中招募，还会从马里兰州、华盛顿特区和弗吉尼亚州丰富的历史黑人学院和大学中招募。动态网页、活跃的研讨会系列和年度开放日将成为我们向科学界和非技术界传播我们的研究成果的关键渠道。该项目的资金由数学和物理科学理事会的物理司以及计算机和信息科学与工程理事会的计算和通信基金会司提供。

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.
