CAREER:Quantum Optics with Magnetic Molecular Spins, an Integrated Approach for Basic Science Research and Education

非技术摘要分子自旋很有可能被用于未来微米级的设备中，涉及信息技术的经典或量子方面。最近有研究表明，在特定条件下，“人造”自旋可以表现出量子力学的行为。佛罗里达州立大学教师早期职业发展(CALEAR)项目的目标是研究强耦合到共振光子的分子自旋的量子动力学，着眼于信息技术领域的潜在实施。自旋探测将通过将自旋耦合到特殊设计的微腔内的电磁场来完成。实现单自旋灵敏度是一个重要的目标，以及了解分子样品中的退相干机制。通过与NHMFL的联合，一个广泛的凝聚态社区将与拟议的研究密切互动。这项研究的具体内容将有利于本科生和研究生的培养，部分技术将被整合到物理实验方法研究生课程中。该计划将支持NHMFL最近的一项倡议，即开发一个名为SuperNet的全国网络，该网络将为高中提供物理演示模块。技术摘要佛罗里达州立大学这个教师早期职业发展(CALEAR)项目的目标是研究与共振光子强烈耦合的分子自旋的量子动力学。在这些样本中，与量子宏观性或退相干相关的基本问题近在眼前。还将调查信息技术领域的潜在实施情况。特别是，这项研究将集中在：i)量子非摧毁观测自旋系综，ii)在准简谐自旋态下观察奇异的多光子反共振，以及iii)单自旋灵敏度。这些目标具有重要的科学意义，将给特定环境下自旋的量子动力学带来光明。有人提出在微腔内将分子的总自旋与共振电磁场的B分量耦合，类似于谐振腔与原子或超导量子比特电耦合的情况。通过与NHMFL的联合，一个广泛的凝聚态社区将与拟议的研究密切互动。这项研究的具体内容将有利于本科生和研究生的培养，部分技术将被整合到物理实验方法研究生课程中。该计划将支持NHMFL最近的一项倡议，即开发一个名为SuperNet的全国网络，该网络将为高中提供物理演示模块。

Non-technical AbstractThe molecular spins have a high potential of being used in future micron-scale devices dealing with either classical or quantum aspects of information technology. Recently it has been shown that "man-made" spins can behave quantum mechanically under specific conditions. The goal of this Faculty Early Career Development (CAREER) project at the Florida State University is to investigate the quantum dynamics of molecular spins coupled strongly to resonant photons, with an eye on potential implementations in the information technology field. Spin detection will be accomplished by coupling the spin to an electro-magnetic field inside specially designed microscopic cavities. Achieving single spin sensitivity is an important objective, together with the understanding of decoherence mechanisms in molecular samples. Through association with the NHMFL a broad condensed matter community will interact closely with the proposed research. The specifics of the research will be benefic for the training of undergraduate and graduate students and part of the techniques will be integrated in a graduate course on experimental methods in physics. The program will sustain a recent NHMFL initiative to develop a nation-wide network called SuperNet which will provide high-schools with physics demonstration modules.Technical AbstractThe goal of this Faculty Early Career Development (CAREER) project at the Florida State University is to investigate the quantum dynamics of molecular spins coupled strongly to resonant photons. Fundamental questions related to quantum macroscopicity or decoherence are at hand in these samples. Potential implementations in the information technology field will be investigated as well. In particular, the study will focus on: i) quantum non-demolition observation of an ensemble of spins, ii) observation of exotic multi-photon anti-resonances in quasi-harmonic spin states and iii) single spin sensitivity. These goals have important scientific significance and will bring light to the quantum dynamics of spins in the presence of a given environment. It is proposed to couple the total spin of a molecule to the B-component of a resonant electro-magnetic field inside microscopic cavities similar to the case of resonant cavities electrically coupled to atoms or superconducting qubits. Through association with the NHMFL a broad condensed matter community will interact closely with the proposed research. The specifics of the research will be benefic for the training of undergraduate and graduate students and part of the techniques will be integrated in a graduate course on experimental methods in physics.
