Project Grant 2441238

The National Science Foundation (NSF) awarded a $160,000 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to the Massachusetts Institute of Technology (MIT) for the project "CAREER: MACROSCOPIC QUANTUM MEASUREMENT AND CONTROL TO PROBE GRAVITY." The research aims to perform experiments on centimeter-scale objects to detect and measure gravitational interactions at the quantum scale, which is a challenge in contemporary physics. Specifically, the project will develop techniques to fabricate large, high-quality torsional oscillators as "probe masses" to measure the gravitational force of smaller "source masses." The research will also produce a textbook on the theory and practice of realistic quantum measurements to help train the next generation of quantum engineers. The project period is from February 2025 to January 2030.
