Confining atoms to small spaces alters their properties due to light-matter interactions, surface proximity, and atomic collisions. While atomic vapors are simpler to operate compared to cooled atoms and ions, they are more susceptible to decoherence due to thermal motion.  Our research aims to develop chip-scale quantum memories by understanding how confinement impacts coherence. Through fundamental study of the atom-light interaction with various optical modes and materials, we aim to advance chip-scale quantum communication and computation.
