We report high-precision frequency ratio measurements between optical atomic clocks based on 27Al+, 171Yb, and 87Sr. With total fractional uncertainties at or below 3.2 × 10−18, these measurements meet the milestone criteria for redefinition of the second

Wavefront mapping for absolute atom interferometry

April 10, 2026
Author(s)
Joseph Junca, John Kitching, William McGehee
Wavefront distortions are a leading source of systematic uncertainty in light-pulse atom interferometry, limiting absolute measurements of gravitational acceleration at the 30 nm/s2 level. Here, we demonstrate in situ spatially-resolved measurement of the
