The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...
