Using atomic nuclei could allow scientists to read time more precisely than ever – what this research could mean for future clocks

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

First quantum grandfather clock could probe where gravity comes from

The first complete design for a quantum grandfather clock uses a single atom, tiny mirrors and light. Building it could help our understanding of what makes any clock accurate in the quantum realm and ...
