Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to microwaves, like conventional atomic clocks. The accuracy of these clocks ...

International sanctions can have a paradoxical effect, spurring some nations to push harder to obtain nuclear weapons. Here’s how sanctions can be more effective.

IonQ (NYSE: IONQ), the world's leading quantum company, today announced the successful completion of its acquisition of Vector Atomic, the leading quantum sensing company based in California. The ...

Time can be a controversial business. Who came up with time zones – and why is the International Date Line a bit squiggly?

The Nobel Prize is considered the "Mount Everest of science." But it faces criticism over how winners are chosen, and may give a warped idea of scientific progress.

European and US officials have said that diplomacy remains an option. But Europe's "snapback" of UN sanctions on Iran shrinks the possibility of successful diplomacy and fuels escalation.

Every cell in the human body operates on an intricate internal schedule, governed by circadian rhythms that synchronize our biological processes with the 24-hour cycle of day and night. Coordinated by ...

John Clarke, Michel H. Devoret and John M. Martinis were recognized for work that made behaviors of the subatomic realm observable at a larger scale.

When something dies, a telltale radioactive signal ticks like a natural clock. Discovering it helped us solve all sorts of natural mysteries.

"With this, we can detect very tiny changes in both position and momentum at once, beyond the limit of any classical sensor," the authors explained.
