This National Science Foundation (NSF) Mathematical and Physical Sciences (CFDA 47.049) Project Grant award of $135,430 to the University of Illinois supports research to advance optical atomic clock technology. The work aims to enhance the accuracy and stability of these ultraprecise timekeeping devices by developing techniques to minimize laser noise and measurement uncertainties. Key objectives include demonstrating "mid-circuit" operations to extend clock operation beyond laser coherence time, as well as using optical cavities and quantum entanglement to reduce projection noise. This research has broad societal impact, as it could lead to advances in fault-tolerant quantum computing and quantum network timing systems. The award, which runs from May 2024 to April 2029, provides hands-on research experience for undergraduate and graduate students, helping to grow the U.S. quantum workforce. No subawards are planned under this grant.
