Atoms and molecules have been used to create some of the world's most sensitive sensors, due to their favorable quantum properties. Prior work has shown that atoms trapped in “cryogenic matrices” — frozen gasses such as solid neon and hydrogen — preserve many of these crucial quantum properties, and that it is possible to isolate and interact with single atoms in such solids. In this project, the research team will (1) continue to investigate the properties of atoms and molecules in these cryogenic solids and (2) use them to develop single-atom quantum sensors. This has the potential to not only advance this particular field, but also to develop new sensing tools for other fields of physics, chemistry, and biology. The undergraduate and graduate students working on the project will be trained in experimental techniques with wide applicability in experimental science, particularly in quantum information science.The project has two primary goals. The first is to measure the nuclear spin coherence of ensembles of molecules implanted in solid parahydrogen. These measurements will shed light on the motion of the molecules within the “quantum solid” of parahydrogen. Moreover, if the nuclear spin coherence is favorable, this system will be of use in precision-measurement experiments for improving our understanding of fundamental physics, such as the search for a permanent electric dipole. The second is to use a single rubidium atom implanted in solid neon as a nuclear magnetic resonance (NMR) sensor capable of measure the NMR signal of a single nuclear spin. If successful, this would give scientists the capability of performing NMR measurements of single molecules, a long-sought goal. Additionally, this would be a crucial first step towards developing new methods to image the structure of a single molecule, a potentially transformative technology for chemistry and biology.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.

由于其有利的量子性能，原子和分子已被用来创建一些世界上最敏感的传感器。先前的工作表明，被困在“低温物质”中的原子 - 固体霓虹灯和氢等冷冻气体 - 保留了许多关键的量子特性，并且可以在此类固体中分离并与单个原子隔离并相互作用。在该项目中，研究团队（1）将继续研究这些低温固体中原子和分子的特性，（2）使用它们来开发单原子量子传感器。这不仅有可能推进这一特定领域，还可以为其他物理，化学和生物学领域开发新的传感器工具。从事该项目的本科生和研究生将接受具有实验科学广泛适用性的实验技术培训，尤其是在量子信息科学中。该项目具有两个主要目标。首先是测量植入固体寄生虫的分子集合的核自旋相干性。这些测量结果将阐明偏二氢“量子固体”内的分子运动。此外，如果核自旋连贯性很高，则该系统将用于精确测量实验，以提高我们对基本物理学的理解，例如寻找永久性电偶极子。第二个是使用植入固体霓虹灯的单个rubidium原子作为能够测量单个核自旋的NMR信号的核磁共振（NMR）传感器。如果成功，这将使科学家能够对单分子进行NMR测量，这是一个长期追求的目标。此外，这将是开发新方法以形象单个分子的结构的关键第一步，这是一种潜在的化学和生物学技术变革性技术。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响标准来评估通过评估来诚实地支持支持。
