Researchers at the Ye Lab at JILA (the National Institute of Standards and Technology and the University of Colorado Boulder) and University of Delaware recently created a highly precise optical ...

Precision equipment manufacturer Shimadzu Corp. said it has created the world’s most accurate time device: a clock that won’t ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...

Tucked away in a vault in France is a weight made of platinum and iridium, diligently cared for by a team of highly trained specialists. Its sole purpose is to be, to sit and remain unchanging as the ...

Add Yahoo as a preferred source to see more of our stories on Google. MIT and Harvard scientists have built the world's most precise optical clock, surpassing the quantum limit with entangled atoms ...

Optical clocks represent the forefront of timekeeping and frequency metrology, exploiting ultranarrow electronic or vibrational transitions in atoms or molecules confined by optical potentials. By ...

Timekeeping is an essential underpinning of daily life and a vital component of our social and technological infrastructure. The Japanese optical lattice clock, a top candidate for redefinition of the ...

Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known ...

The challenge of creating the world’s most precise clock is that that even the slightest deviations limit the precision. Atomic clocks, which rely on the coherent evolution of atomic states, are the ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...
