JILA, established by NIST and the University of Colorado Boulder, has played a pivotal role in advancing precision timekeeping through optical atomic clocks. These devices achieve extraordinary time measurement accuracy by utilizing the fundamental properties of atoms. Despite their advancements, the precision of these clocks is limited by quantum projection noise (QPN), arising from the quantum nature of the atoms.
