Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

Researchers in Germany have found a way to accurately study atomic reflections in quantum sensors by deploying special light ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction -- from past to future -- time could flow forward or backward due to processes taking place at the quantum ...

Abstract: High-performance atomic clocks provide the foundation for precise time measurement. Common high-performance atomic clocks in time-keeping laboratories include hydrogen masers and cesium ...

A low-noise chip-scale atomic clock (LN-CSAC), the SA65-LN from Microchip, features a profile height of less than 0.5 in. (12.7 mm). Aimed at aerospace and defense applications where size, weight, and ...

A Chip-Scale Atomic Clock (CSAC) is an essential reference for these systems, providing the necessary precise and stable timing where traditional atomic clocks are too large or power-hungry and ...
