We report the frequency ratio of two optical atomic clocks with a fractional uncertainty of 5.2 × 10 –17. Recently, a regime of operation for atomic clocks based on optical transitions has become possible, promising even higher performance.
This precision enables tests of fundamental physics and cosmology, as well as practical applications such as satellite navigation.
Time has always had a special status in physics because of its fundamental role in specifying the regularities of nature and because of the extraordinary precision with which it can be measured.
