strontium clock

JILA's recent advancements in the precision of strontium optical lattice clocks have garnered significant recognition, with Physics World Magazine highlighting their achievement. The research team from JILA and the University of Colorado, Boulder, has set a new record in measuring the frequency of an optical lattice clock with an unprecedented systematic uncertainty of 8.1 × 10⁻¹⁹. This level of precision is equivalent to a fraction of a second over the entire universe age, underscoring the importance of this development in the field of atomic clocks.
