JILA?s three-dimensional (3-D) quantum gas atomic clock consists of a grid of light formed by three pairs of laser beams. A stack of two tables is used to configure optical components around a vacuum chamber. Shown here is the upper table, where lenses and other optics are mounted. A blue laser beam excites a cube-shaped cloud of strontium atoms located behind the round window in the middle of the table. Strontium atoms fluorescence strongly when excited with blue light.

Jun Ye interview: What use is the world’s most accurate clock?

The most advanced atomic clocks don鈥檛 just tell time 鈥� they could soon get so ludicrously accurate that they could be used for detecting gravitational waves and testing the limits of relativity
