Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the ...

The new research controls the noise in atomic frequency to double the precision of atomic clocks for a more accurate time.

The latest optical atomic clocks use faster atoms such as ytterbium, which tick up to 100 trillion times per second. However, their stability has been restricted by quantum noise, ...

A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Inside a laboratory nestled in the foothills of the Rocky Mountains, amid a labyrinth of lenses, mirrors, and other optical machinery bolted to a vibration-resistant table, an apparatus resembling a ...

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...

In the world we live in, time is far more than just the clock on the wall. From financial transactions to power grids, from communication stations to scientific research, the efficient collaboration ...
