As well as being useful for creating an optical ion clock, this multi-ion capability could also be exploited to create quantum-computing architectures based on multiple trapped ions. And because the ...

Magnetic field and bias voltage sweeps at two current set points. White dashed lines indicate spline-interpolated ESR peak positions. Panels c and d show g-factor and tip field vs. bias voltage for ...

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 ...

Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers are now pushing ...

Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have stretched a chain of gold ...

WASHINGTON — Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks ...

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...
