This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Coherent electromagnetic radiation in the form of laser light holds enormous promise for future information technology but only if suitable materials capable of capturing and efficiently maintaining the coherence can be found or developed.Our idea is to investigate strong coupling between the optical field and the quantum system that may be achieved in the limit of purely radiative decay of the excited states. This project will perform experiments to study the formation and dissipation of the coherence in a special class of crystalline materials containing resonantly absorbing rare earth ions having promising nearly radiative-limited decoherence properties.The goal is to find a solid material that would allow a large number of operations (instead of currently feasible few operations) before the system loses track of its coherent or entanglement state. If successful, such systems will provide the key components of future quantum super-computers as well as eavesdropping-proof data communication systems.Broader impacts of the work will include the training of students in these fields and collaborations with local technological industry.

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.Coherent电磁辐射以激光灯的形式对未来的信息技术有着巨大的希望，但仅当适合捕获并有效地保持连贯性的材料时可以找到或开发。我们的思想是研究光场和量子系统之间的强耦合，这些系统可以在激发态纯粹的辐射衰变的极限下实现。该项目将执行实验，以研究一类特殊类型的结晶材料的形成和耗散，这些材料含有共鸣，吸收了有望几乎具有辐射限制的脱碳特性的稀土离子。该目标是找到可以允许大量数量的固体材料在系统失去其连贯或纠缠状态之前的操作（而不是当前可行的操作）。如果成功的话，此类系统将提供未来量子超级计算机的关键组成部分，以及窃听的数据通信系统。这项工作的影响将包括对这些领域的学生进行培训以及与本地技术行业的合作。
