Cesium atomic clocks are some of the most accurate time-keeping devices ever made, but the newest generation of clocks render ...

Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both uploaded as preprints, report reliable timekeeping ...

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 ...

For decades, physicists have pursued a goal that sounds nearly impossible: to build a clock that keeps time using an atom's nucleus rather than the electrons orbiting it. "Having worked in this field ...

IonQ has secured a $28 million contract extension from the Defense Advanced Research Projects ...

Imagine you're trying to keep time by listening to a room full of people clapping. If everyone claps randomly, it’s hard to tell the rhythm. But if they clap in sync, the beat becomes clear and steady ...

Pictures of the components used in making an atomic clock. The ion trap (left image) holds the clock in place. The optical/laser apparatus (right images) measures the clock’s frequency. Fukuoka, Japan ...

DARPA selected IonQ to create a manufacturing pipeline for rugged optical atomic clocks that could preserve precise military ...

IonQ (NYSE: IONQ) clarifies its announcement that it has been awarded a $28 million contract extension, with an additional option of $30 million through the Defense Advanced Research Projects Agency ...

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...

Einstein had some pretty crazy theories about time, and two scientists set out to test them by taking a long flight on a commercial airliner.
