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.

A tomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It outweighs everything we see by a factor of five, yet it slips past every detector ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

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 ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch. Where and why tiny, portable, ...
