The most precise atomic clock ever made has been created by arranging strontium atoms in a grid-like pattern.

In 2014, the world’s most accurate optical clock wouldn’t lose or gain one second in the entire age of the universe says Jun Ye at the University of Colorado at Boulder. Previous cesium clocks kept time accurately to within a second over the course of 300 million years.

Now, Ye’s group has built a strontium clock that is so precise, out of every 10 quintillion ticks only 3.5 would be out of sync – the first atomic clock ever to reach that level of precision.

To build a more precise clock, Ye and his team designed a 3D structure that let them measure signals from more atoms at once within the width of the laser beam.

Now the most precise atomic clock ever made using a cube (3D) of quantum gas gives the most accurate time.
