http://www.cardinalxtal.comThe term “frequency jitter” has become popular in the last few years to define the short-term stability of a frequency source. A ...

We think of crystals as the gold standard of frequency generation. However, if you want real precision, you need something either better than a crystal or something that will correct for tiny errors — ...

A next-generation atomic clock that tops previous records for accuracy in clocks based on neutral atoms has been demonstrated. The new clock, based on thousands of strontium atoms trapped in grids of ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

Polish physicists have been aiming to build an optical atomic clock, an extremely precise device with an accuracy of one second in a few dozen billion years, since 2008. The last of the three key ...

Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...
