"replaces free-space lasers/ optics generating beams manipulated by lenses, mirrors modulators, combined with magnetic coils/ atoms in vacuum, creating cold atoms... compact optics/ integrated photonics embedded into low-loss silicon nitride waveguide integration platform... atomic cell vacuum chamber... larger the beams the more atoms trapped into cloud and interrogated... sensing faint electromagnetic signals/ fundamental particles, precision timekeeping/ navigation, quantum computing"
