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 ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...

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 ...

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 ...

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 ...

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