A Framework for Realizing a Microscopic, Highly Precise and Energy-Efficient Quantum Clock

A framework for realizing a microscopic, highly precise and energy-efficient quantum clock

Over the past decades, physicists have been trying to develop increasingly sophisticated and precise clocks to reliably measure the duration of physical processes that unfold over very short periods of time, helping to validate ...

Scientists are redefining time itself, starting with the second

Switching to optical clocks would have cascading ripple effects from meteorology to basic physics.

10 Atomic Clocks Connected Across 6 Countries In Most Ambitious Timekeeping Experiment Ever

Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn't lose or gain a second for billions of years. The post 10 Atomic Clocks Connected Across 6 Countries In Most Ambitious Timekeeping Experiment Ever appeared first on Study Finds.

Unprecedented optical clock network lays groundwork for redefining the second

In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six countries. Spanning thousands of kilometers, the experiment represents a significant step toward redefining the second and ultimately establishing a global optical time scale.
