The demonstrated system achieved short-term fractional frequency stability highlighting the platform’s potential for future chip-scale quantum ...

How does a clock become precise enough to guide a spacecraft across interstellar distance without drifting a single second ...

From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by ...

Rushing to get to work in the morning, we grab our coat, bag and keys and – invariably – steal a glance at the clock to check that we are running on time. The passing of time is so integral to our day ...

Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...

(Santa Barbara, Calif.) — In an ongoing effort to bring quantum science out of the tightly controlled lab environment and into the field, researchers from UC Santa Barbara and the University of ...
