项目摘要
With support from the Chemical Structure, Dynamics & Mechanisms-B (CSDM-B) Program of the Chemistry Division, Professors Mykhailo Shatruk of the Department of Chemistry and Biochemistry and Stephen Hill of the Department of Physics and National High Magnetic Field Laboratory at Florida State University are investigating approaches to magnetic molecules that can serve as qubits for quantum information processing. The project focuses on lanthanide complexes with quantum clock transitions, which can provide protection of the molecular qubits against external magnetic noise and prolong the duration of quantum entanglement – a crucial factor for the implementation of quantum technologies. The project will train junior scientists at the nexus of inorganic chemistry, quantum physics, and materials science, thus contributing to the education of the future quantum workforce. The project team plans to organize a nationwide undergraduate summer school to educate students about magnetic materials. Outreach activities will also involve high-school students and the general public, and are aimed at broadening participation by members of groups underrepresented in physical sciences.Paramagnetic molecular complexes are promising platforms for the development of electron spin qubits, due to the high tunability of their synthesis that allows realization of targeted magnetic parameters. This project will involve the examination of lanthanide complexes as potential electron spin qubits, with a focus on quantum clock transitions (QCTs) that emerge from the opening of quantum tunneling gaps due to mixing of ground doublet states generated by crystal field splitting. At the QCT, electron spin becomes insensitive to the surrounding spin bath, leading to a dramatic increase in the quantum coherence time, thus allowing protection of the entangled state from the magnetic noise. The first stage of this project involves the investigation of mononuclear complexes to identify the most promising QCT systems that demonstrate the desired values of tunneling gap and coherence time. The second stage will be devoted to connecting such qubits through a photo- or redox-switchable linkers, to make possible quantum gate operations. Advanced characterization methods, including a suite of electron paramagnetic resonance techniques, far-infrared magnetic spectroscopy, inelastic neutron scattering, and theoretical modeling will be used to investigate the molecular qubits and guide further synthetic efforts.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
在化学系化学结构、动力学和机理-B (CSDM-B) 项目的支持下,佛罗里达州立大学化学与生物化学系的 Mykhailo Shatruk 教授以及物理系和国家强磁场实验室的 Stephen Hill 教授大学正在研究可用作量子信息处理量子位的磁性分子的方法,该项目重点研究具有量子时钟跃迁的镧系元素络合物,它可以为分子量子位提供保护。对抗外部磁噪声并延长量子纠缠的持续时间——这是实施量子技术的关键因素,该项目将培训无机化学、量子物理和材料科学领域的初级科学家,从而为教育做出贡献。该项目团队计划组织一个全国范围内的本科生暑期学校,对学生进行有关磁性材料的宣传活动,该活动还将涉及高中生和公众,旨在扩大物理领域代表性不足的群体成员的参与。顺磁性分子。配合物是开发电子自旋量子位的有前途的平台,因为它们的合成具有高度可调性,可以实现目标磁参数。该项目将涉及将镧系元素配合物作为潜在的电子自旋量子位进行检查,重点是量子时钟跃迁。 (QCT)是由于晶体场分裂产生的基双态混合而从量子隧道间隙的开口中出现的。在 QCT 中,电子自旋对周围的自旋浴变得不敏感,导致量子的急剧增加。该项目的第一阶段涉及单核配合物的研究,以确定最有前途的 QCT 系统,以证明隧道间隙和相干时间的期望值。该阶段将致力于通过光或氧化还原可切换连接器连接这些量子位,以使先进的表征方法成为可能,包括一套电子顺磁共振技术、远红外磁光谱、非弹性中子散射和理论模型将用于研究分子量子位并指导进一步的合成工作。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
