One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may finally provide some answers.

Unveil the advancements behind the most accurate atomic clock. Learn how it computes time more accurately than ever before.

A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

He worked to develop an atomic clock that is essential to global positioning systems and helped confirm a rare state of matter predicted based on work by Albert Einstein.

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies.

It is controlled from a single user-interface; any of Toptica’s tunable diode lasers with a wavelength between 420 nm and 2000 nm can be locked to the frequency comb. and frequency-doubled lasers with ...

Earlier on June 2, Adtran announced the expansion of its Oscilloquartz optical cesium portfolio with the introduction of the new OSA 3200 SP and OSA 3250 ePRC atomic clocks.

Scientists believe this method yields far more accurate results than the cesium atomic clocks, which have been the global standard for the past five decades.

The pendulum of a pendulum clock generates a little heat and disorder among the air molecules around it, and every laser beam that reads the state of an atomic clock generates heat, radiation and ...

Adtran expands Oscilloquartz atomic clock portfolio with lower-cost optical cesium solutions for wider market adoption Jun. 02, 2025 8:00 AM ET ADTRAN Holdings, Inc. (ADTN) ...

Adtran today launched the latest additions to its Oscilloquartz optical cesium portfolio, expanding access to precision timing across a wider range of network environments. The new OSA 3200 SP and ...
