Our quantum optics theory group primarily explores light-matter interactions in cold quantum gases, with a focus on quantum sensing, open quantum systems, and applying machine learning to quantum design problems. The group collaborates with experimentalists at JILA to develop quantum metrology platforms that utilize interparticle entanglement to sense with a quantum advantage. In addition, the group is part of NASA’s Quantum Pathways Institute to manufacture space-bound quantum-based instruments to be used for navigation and climate science. A focal point of our group's metrology research is utilizing Lie group symmetries to extend entanglement generation protocols to higher dimensional systems. The group also works on bad-cavity QED systems to help realize a continuous-wave superradiant laser that would have a coherence length stretching from the Earth to the Sun, which would help enable the development of active atomic clocks.
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
