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 ...

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 ...

Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173 Yb + has attracted growing interest because of its ...

Highly charged ions are a common form of matter in the cosmos, where they are found, for example, in the sun or other stars. They are so called because they have lost many electrons and therefore have ...

IonQ is actively developing quantum algorithms to tackle complex challenges that are currently insurmountable for classical computing systems. The company's approach focuses on using atomic ions as ...

Gold nanoclusters can now rival trapped atomic ions in quantum performance, offering scalable, tunable building blocks for next-generation devices. Credit: AI/ScienceDaily.com The efficiency of ...

Precision measurements in atomic and ion physics have become a cornerstone for testing the limits of our understanding of quantum electrodynamics (QED) and the Standard Model. By harnessing ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

Internal energy levels of a single atom represent nature’s perfect qubit – the quantum two-level system that is the building block of quantum computing technology. At the Duke Quantum Center, we trap ...

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