A Chip that Keeps Time (Almost) Like an Atomic Clock

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

How ultraprecise ‘nuclear clocks’ could transform timekeeping

Claire Cramer, the executive director of quantum science at the University of California, Berkeley, who was in attendance, expressed optimism about the potential of solid-state nuclear clocks: “This ...

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.
