Title: {sup 87}Sr Lattice Clock with Inaccuracy below 10{sup -15}

Abstract

Aided by ultrahigh resolution spectroscopy, the overall systematic uncertainty of the {sup 1}S{sub 0}-{sup 3}P{sub 0} clock resonance for lattice-confined {sup 87}Sr has been characterized to 9x10{sup -16}. This uncertainty is at a level similar to the Cs-fountain primary standard, while the potential stability for the lattice clocks exceeds that of Cs. The absolute frequency of the clock transition has been measured to be 429 228 004 229 874.0(1.1) Hz, where the 2.5x10{sup -15} fractional uncertainty represents the most accurate measurement of a neutral-atom-based optical transition frequency to date.
