This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award supports experimental research investigating quantum information using nuclear spin. In quantum information research, atomic gases have been successfully used in many important applications. Prior experiments using atomic ensembles stored quantum information in electron spin. Unfortunately, electron spin is fragile, and information can be easily lost. On the other hand, nuclear spin is comparatively robust. This project will develop techniques for entangling photons with a nuclear ensemble and for storing quantum information in nuclear spin. The project will explore the coherence between photons and nuclei, and use nuclear spin to implement the basic building blocks of ensemble-based quantum information experiments.The broader impact of this program includes the training of graduate and undergraduate students in cold atom research, quantum information research, and many areas of modern technology, such as lasers, optics, high vacuum, and cryogenics. The fundamental concepts underlying the research will be disseminated to a wider audience of students using the internet. Potential practical applications include the development of long-distance secure quantum-cryptographic communication and the ability to network quantum computers.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。该奖项支持实验研究，使用核旋转调查量子信息。 在量子信息研究中，原子质已经成功地用于许多重要应用中。 先前使用原子集合在电子自旋中存储量子信息的实验。 不幸的是，电子旋转是脆弱的，并且信息很容易丢失。 另一方面，核自旋相对稳健。 该项目将开发用于将光子与核合管纠缠的技术，并将量子信息存储在核旋转中。 该项目将探索光子和核之间的相干性，并使用核自旋来实施基于合奏的量子信息实验的基本构件。该计划的更广泛影响包括在冷原子研究，量子信息研究中培训研究生和本科生，以及现代技术的许多领域，例如Lasers，Optics，Optics，Optics，Optics，Optics，Optics，Agg Age Vacuum和Cryogent和seryogent和seryogent和seryogent和seryogent和seryogent和cryogent和cryogent和cryogent和cryogent和cryogent和cryogenation。 研究基础的基本概念将通过互联网传播给更多的学生。 潜在的实际应用包括开发长距离安全的量子 - 元素通信和网络量子计算机的能力。
