This $576,000 National Science Foundation (NSF) Chemical Structure and Dynamics (CSD) Program Project Grant is supporting Professor Hendrik Utzat of the University of California, Berkeley to advance a new form of spectroscopy for studying decoherence in single-photon emitters critical to quantum information science (QIS) technologies. The research leverages Hong-Ou-Mandel spectroscopy to disentangle the roles of charge and spin noise in decoherence for single emitters within boron nitride monolayers and metal halide perovskite quantum dots. The project aims to uncover the atomistic origins of dephasing mechanisms and develop materials design principles to suppress decoherence, leading to higher-quality single-photon emitters. In addition, the program supports the development of a quantum-educated U.S. workforce through an extracurricular science workshop for high school students. No sub-awards are planned under this grant, which has an ultimate completion date of February 28, 2030.
