MIT researchers double the accuracy of optical atomic clocks by reducing quantum noise with an innovative laser technique.

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...

Time is vital to the functioning of our everyday lives: from the watches on our wrists to the GPS systems in our phones. Communication systems, power grids, and financial transactions all rely on ...

BOULDER, Colo. — It was close to midnight on a Wednesday in May when physics graduate student Chuankun Zhang fired a specialized laser at a tiny radioactive crystal nestled in a vacuum chamber and was ...

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known as NIST-F4, ...

METAS needed a precise, reliable timing solution to complete its infrastructure, realize the Swiss national timescale UTC (CH) and optimally contribute to the realization of UTC Adtran’s OSA 3300 HP ...

Researchers from six countries conducted the largest coordinated comparison of optical clocks to date. The measurements amount to the largest coordinated comparison of optical clocks to date, and ...

New Oscilloquartz models bring advanced optical pumping technology to telecom, defense, data center and metrology networks Adtran’s unique cesium clock solutions deliver longer service life and ...

A new atomic clock will keep data center equipment precisely synchronized for months, if global time services including GPS are unavailable or blocked. The 5071B cesium atomic clock from Microchip ...

“With our precision timing module, we’re setting new benchmarks in short-term frequency stability, addressing the critical demands of sectors ranging from scientific research labs to aerospace ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...
