****Technical Abstract****The present proposal is focusing on implementing techniques closely related to quantum optics in solid-state systems containing diluted, highly coherent spins. The control of dynamics of spins in solid-state materials has direct implications at both fundamental and applied levels. Research topics, in particular quantum computing, rely heavily on both complex control techniques and long spin coherence times to achieve intricate and robust information control. One aspect of this proposal is to identify new supramolecular structures with long spin coherence times. A natural way of driving spin orientation is by using electromagnetic fields (photons) and it can be done either as a classical rotation or by entanglement with the field itself. The studies are to be performed at very low temperatures, using on-chip, superconducting devices (planar cavities and micro-squids). The present program will train undergraduate and graduate students, sustain PI's involvement in the Research Experience for Undergraduates and Teachers programs, and in the development of scientific demonstrations at outreach events in the FSU and NHMFL campuses****Non-Technical Abstract****Modern technological applications are aiming closer and closer to a limit where quantum mechanics is the main theoretical tool. Often, electronic chips and small components are involved in such applications. At the same time, an impressive amount of research has been done in the case of atoms in dilute gases, since such systems are governed purely by Quantum Mechanics. Here, we propose to implement techniques of quantum optics into the field of solid-state physics, to develop new experimental tools. Also, we will search for new supramolecular materials capable of sustaining for long times quantum information, for on-chip applications like Quantum Computing. The studies are to be performed at very low temperatures, using on-chip, superconducting devices (planar cavities and micro-squids). This research is intrinsically connected to the act of teaching: if we teach our students well, we will have top scientists in the future. The present program will train undergraduate and graduate students, sustain PI's involvement in the Research Experience for Undergraduates and Teachers programs, and in the development of scientific demonstrations at outreach events in the FSU and NHMFL campuses. Moreover, through association with the NHMFL, a broad condensed matter community (users, visitors, and students) will interact closely with the proposed research.

*技术摘要*本提案的重点是在包含稀疏、高度相干自旋的固态系统中实现与量子光学密切相关的技术。固体材料中自旋动力学的控制在基础和应用两个层面都有直接的意义。研究课题，特别是量子计算，在很大程度上依赖于复杂的控制技术和长自旋相干时间来实现复杂而稳健的信息控制。这一提议的一个方面是识别具有长自旋相干时间的新的超分子结构。驱动自旋取向的一种自然方法是使用电磁场(光子)，这可以通过经典的旋转或通过与场本身的纠缠来完成。这些研究将在非常低的温度下进行，使用芯片上的超导设备(平面腔和微型鱿鱼)。本计划将培养本科生和研究生，保持PI对本科生和教师项目的参与，以及在FSU和NHMFL校园的外展活动中开发科学演示*非技术摘要*现代技术应用的目标是越来越接近以量子力学为主要理论工具的极限。通常，电子芯片和小型部件都涉及到这种应用。与此同时，对于稀薄气体中的原子，人们已经做了大量令人印象深刻的研究，因为这类系统纯粹是由量子力学管理的。在这里，我们建议将量子光学技术应用于固体物理领域，以开发新的实验工具。此外，我们还将寻找能够长期支持量子信息的新的超分子材料，用于量子计算等芯片应用。这些研究将在非常低的温度下进行，使用芯片上的超导设备(平面腔和微型鱿鱼)。这项研究与教学行为有着内在的联系：如果我们教得好我们的学生，我们就会有未来的顶尖科学家。目前的计划将培训本科生和研究生，支持PI参与本科生和教师研究经验计划，并在FSU和NHMFL校园的外联活动中发展科学示范。此外，通过与NHMFL的联合，一个广泛的凝聚态社区(用户、访问者和学生)将与拟议的研究密切互动。
