Coherent Dynamics of Spins Placed in Quantized Electromagnetic Fields and Studied Using Superconducting Device

****技术摘要****本提案的重点是在包含稀释的高相干自旋的固态系统中实现与量子光学密切相关的技术。固体材料自旋动力学的控制在基础和应用层面都具有直接意义。研究课题，特别是量子计算，严重依赖于复杂的控制技术和长自旋相干时间来实现复杂和鲁棒的信息控制。这一建议的一个方面是确定具有长自旋相干时间的新超分子结构。驱动自旋方向的一种自然方法是使用电磁场（光子），它既可以作为经典旋转也可以通过与场本身的纠缠来实现。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（平面腔和微型乌贼）。本计划将培养本科生和研究生，维持PI参与本科生和教师研究经验计划，并在FSU和NHMFL校园的推广活动中发展科学演示****非技术摘要****现代技术应用的目标越来越接近极限，其中量子力学是主要的理论工具。通常，电子芯片和小型元件都涉及到这类应用。与此同时，由于这种系统完全由量子力学控制，人们对稀气体中的原子进行了大量令人印象深刻的研究。在此，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，我们将寻找能够长时间维持量子信息的新型超分子材料，用于芯片上的应用，如量子计算。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（平面腔和微型乌贼）。这项研究与教学行为有着内在的联系：如果我们把学生教得好，我们将来就会有顶尖的科学家。目前的项目将培训本科生和研究生，维持PI参与本科生和教师研究经验项目，并在FSU和NHMFL校园的外展活动中发展科学演示。此外，通过与NHMFL的联系，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。

****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.
