Abstract: Accurate timing is critical in many industries, from time-stamping grocery receipts to facilitating stock-market transactions and supporting precise navigation, localization, and guidance.

Abstract: In this paper, we propose a new time scale generation algorithm from an ensemble of hydrogen maser-type atomic clocks by using tools from control theory. We consider another ensemble of ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that are used for GPS navigation, satellite communication, and testing fundamental physics depend on carefully controlled ...

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 ...
