But that could change. Suggestss because test these clocks could be three times as accurate as current atomic clocks. Clock is not just a single clock with a single atom. It is a collection of clocks working together and using laser beams by giving higher frequency. The higher frequency is a better chance you have of getting an accurate measure of a second.
