Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible with simultaneous ...

Quantum clocks break energy limits, unlocking ultra-precise timekeeping with far-reaching tech, AI, and navigation impacts.

The clock design proposed by the researchers is based on quantum many-body systems, where particles behave in coordinated, wave-like patterns. This kind of collective behavior allows for precise ...

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 atomic clocks.

Advances in technology to support AI and edge computing will likely drive a shift away from quartz timing toward silicon MEMS ...

The crucial point is using two different time scales—similar to how a clock has a second hand and a minute hand. The paper is published in the journal Nature Physics.

WASHINGTON — Researchers have shown, for the first time, that transmission of ultrastable optical signals from optical clocks across tens of kilometers of deployed multicore fiber is compatible ...

Optical clocks are incredibly precise, but they are also highly complex. There are just around 100 of them in existence worldwide, largely because they are difficult to build, operate, and ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

By comparing optical clocks in six different countries, researchers have taken a major step toward establishing a new global ...

They said, ‘We’re going to shoot them. Is one o’clock OK?' I said it’s fine," Trump said during a recent NATO summit.
