Quantum network would be most precise clock yet

Physicists propose harnessing ‘quantum entanglement’ to surpass accuracy of any single atomic clock.

By exploiting the tricks of quantum physics, researchers say they could build a worldwide network of atomic clocks that are much more accurate than any single clock in existence today.

This global hook-up would enable countries to synchronize timekeeping standards and improve space navigation. It could also aid the exploration of fundamental physics concepts, such as the long-sought gravitational waves thought to be rippling through space and time.
