<p>Superprecise timekeepers based on atomic nuclei could be tested as soon as this year</p>
Nuclear clocks are highly precise timekeeping devices that utilize the vibrations of atomic nuclei to measure time. They have the potential to surpass the accuracy of current atomic clocks, making them valuable for applications in fundamental physics and technology.
Atomic transitions refer to the process by which an electron moves between energy levels within an atom. This phenomenon is fundamental to the operation of atomic clocks, as the frequency of these transitions can be used to define a second, making them crucial for precise timekeeping.
