Quantum information science has emerged as a revolutionary new paradigm in information technology whose impact could span all society. Successful physical implementation of devices capable of storing and manipulation information stored in quantum systems could lead to exponentially more powerful computers and absolutely secure cryptography. The work to be performed under this award will merge two complementary technologies at the forefront of quantum information science: trapped atomic ions and cavity-QED. Individual trapped ions are unmatched in their performance as quantum memories, and single photons are the only realistic carrier of quantum information between remote locations. A scalable trapped ion + cavity system capable of storing, manipulating, and transmitting quantum information over large distances will be developed. The significant technical hurdles challenging the objectives of this work will be systematically studied, and the state-of-the-art in critical underlying technologies will be advanced through a close collaboration with key industrial companies and fabrication facilities. A theoretical component will explore coupling strategies between atomic and photonic qubits, while supporting the experimental program with realistic models of actual devices.

量子信息科学已经成为信息技术的一个革命性的新范式，其影响可能跨越整个社会。能够存储和操纵存储在量子系统中的信息的设备的成功物理实现可能会导致更强大的计算机和绝对安全的密码学。该奖项下的工作将融合量子信息科学前沿的两种互补技术：捕获原子离子和腔QED。单个捕获离子作为量子存储器的性能是无与伦比的，单光子是远程位置之间量子信息的唯一现实载体。将开发一种能够在大距离上存储、操纵和传输量子信息的可扩展的捕获离子+腔系统。将系统地研究挑战这项工作目标的重大技术障碍，并通过与主要工业公司和制造设施的密切合作，推进关键基础技术的最新发展。理论部分将探索原子和光子量子位之间的耦合策略，同时支持实际设备的现实模型的实验程序。
