This research develops tabletop methods for studying rare radium-containing molecules to search for broken symmetries between matter and antimatter. Because radium’s asymmetric nuclear structure strongly amplifies subtle physical effects, these molecules provide highly sensitive probes for new physics that could help explain why matter exists in the universe after the Big Bang.

This research scales neutral-atom quantum computing using optical tweezer arrays containing over 6,100 cesium atoms trapped across 12,000 tweezers. The work demonstrates record coherence times, high-fidelity atom detection, and controllable atom movement, advancing the development of large-scale quantum computers capable of quantum simulation, computation, sensing, and networking.
