This Research Infrastructure Improvement Track-4 EPSCoR Research Fellows project will provide a fellowship to an Assistant Professor and training for one graduate student per project year at the University of Nevada Las Vegas (UNLV). This work will be conducted in collaboration with researchers at the National Institute for Standards and Technology (NIST). Pioneered by NIST in 2005, Quantum Logic Spectroscopy (QLS) stands as a revolutionary methodology enabling universal quantum control and detection of ions and has significantly impacted the fields of precision measurements. This fellowship aims to facilitate the transfer of QLS technology and expertise from NIST to UNLV. This objective will be realized through multiple means. The PI and graduate students will make several visits, each extending about a few months, to NIST. This will allow the researchers to gain hands-on experience and interact with NIST experts, while also having persistent efforts to establish a QLS experimental platform at UNLV. The anticipated outcomes will be multifold. First, a functional QLS platform will be established at UNLV. Second, a robust connection between NIST and UNLV will be created. Third, two experienced graduate students will be developed at UNLV. Fourth, scientific outputs in quantum control and state readout of heavy molecular ions will be generated. Fifth, the groundwork will be prepared for a research and education center dedicated to quantum science at UNLV. As a leading research focus in both fundamental studies and industrial applications, quantum science research initiated by this EPSCoR fellowship presents substantial career opportunities and can play a crucial role in enhancing the diversity of recruitment and systematic retention of women, underrepresented minorities, and first-generation college students in science and engineering. The PI’s research group at UNLV focuses on developing extremely sensitive quantum sensors using molecular ions to explore new physics beyond the Standard model. Although QLS technology has significantly advanced precision measurements in atomic clocks, highly charged ions, and molecular ions, its applications in testing fundamental symmetries, such as exploring CP-violating effects, remain unexplored. The primary challenge arises from the incompatibility between a biased electric field necessitated for CP-violating measurements and the motional entanglement required by the QLS scheme. To overcome this obstacle, the PI's group at UNLV has proposed an innovative rotation-induced quantum control protocol. By incorporating the QLS scheme into this newly proposed precision metrology approach, it is possible to greatly enhance the sensitivity of CP-violating measurements. This, in turn, could lead to the discovery or constraint of new physics beyond the Standard Model. Furthermore, this method could be applicable to a wide range of molecular species, such as 232ThF+, 229ThF+, 181TaO+, and 175LuOH+. The capability of investigating generic molecular species enables opportunities to study broad questions in fundamental physics in parallel. With the support of this fellowship, the PI’s group has opportunities to develop a designated QLS platform for precision spectroscopy of 181TaO+ with strong support from NIST. This constitutes a critical step towards ushering in a new era of CP-violation measurements. Moreover, introducing QLS technology will enable research activities at UNLV focused on studying actinide chemistry in terms of spectroscopy and chemical reactivity.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.

该研究基础设施改进 Track-4 EPSCoR 研究员项目将为内华达大学拉斯维加斯分校 (UNLV) 的助理教授提供奖学金，并在每个项目年培训一名研究生。这项工作将与内华达大学拉斯维加斯分校 (UNLV) 的研究人员合作进行。美国国家标准与技术研究所 (NIST) 于 2005 年首创量子逻辑光谱 (QLS)，它是一种革命性的方法，可实现离子的通用量子控制和检测，对精密测量领域产生了重大影响。奖学金旨在促进 QLS 技术和专业知识从 NIST 向 UNLV 的转移，PI 和研究生将多次访问 NIST，每次访问时间约为几个月。获得实践经验并与 NIST 专家互动，同时不断努力在 UNLV 建立 QLS 实验平台。 预期成果将是多方面的。 NIST 和 UNLV 之间将第三，将在 UNLV 培养两名经验丰富的研究生。第四，将产生量子控制和重分子离子状态读出方面的科学成果。第五，将为专门从事量子科学的研究和教育中心奠定基础。作为基础研究和工业应用领域的领先研究重点，EPSCoR 奖学金发起的量子科学研究提供了大量的职业机会，并且可以在增强招聘多样性和系统保留女性、代表性不足的少数族裔和女性方面发挥关键作用。第一代大学生UNLV 的 PI 研究小组高度专注于使用分子离子开发极其敏感的传感器，以探索标准模型之外的新物理，尽管 QLS 技术在原子钟、带电离子和分子离子方面的精确测量具有显着的进步。在测试基本对称性方面的应用，例如探索 CP 破坏效应，主要挑战来自于 CP 破坏测量所需的偏置电场与运动纠缠之间的不相容性。为了克服这一障碍，UNLV 的 PI 小组提出了一种创新的旋转诱导量子控制协议，通过将 QLS 方案融入到这种新提出的精密计量方法中，可以大大提高 CP 的灵敏度。 -违反测量，这反过来可能导致标准模型之外的新物理的发现或限制。此外，该方法可适用于广泛的分子种类，例如 232ThF+、229ThF+、 181TaO+ 和 175LuOH+ 的研究能力使我们有机会并行研究基础物理中的广泛问题。在该奖学金的支持下，PI 团队有机会在强有力的支持下开发用于 181TaO+ 精密光谱的指定 QLS 平台。这是迈向 CP 违规测量新时代的关键一步。此外，引入 QLS 技术将使 UNLV 的研究活动能够专注于研究。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。
