What costs more energy — running a quantum clock or observing it?
Keeping track of time seems simple. A watch ticks, a pendulum swings, and a calendar flips. But at the quantum level, marking time is far more complicated — and far more expensive than anyone expected ...
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 ...
This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...

These atomic clocks wouldn’t lose a second in 13.8 billion years
The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In ...
The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...
A new chart for highly charged ions (HCIs) has been proposed, aiming to replicate the conventional periodic table’s ...

Tiny intrinsic time fluctuations could limit ultimate clock precision: Study
A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...
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 ...
