Scientists have accomplished the most extensive coordinated comparison experiment of optical atomic clocks to date, with multiple optical clocks operating in unison across six nations, resulting in 38 sets of frequency comparisons. For the first time, the experiment utilized multiple link technologies to simultaneously contrast various optical clocks, furnishing a crucial foundation for redefining the "second." Optical clocks surpass cesium clocks in precision and are anticipated to propel advancements in modern technologies, including GPS, power grid dispatch, and financial transactions, as well as future scientific explorations.
