Breakthrough could pave the way for next-generation GPS in drones, smartphones and self-driving cars, scientists say.

Like the teeth of a comb, a microcomb consists of a spectrum of evenly distributed light frequencies. Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, ...

Mesa Quantum wants to shake up GPS by putting quantum sensors in devices as small as a phone and as large as a data center. The Boulder, Colorado-based startup is working on a suite of chip-scale ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

No audio available for this content. A roundup of recent products in the GNSS and inertial positioning industry from the July 2024 issue of GPS World magazine. The Meridian mobile mapping system ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

The US Air Force is turning to atomic clock technology to help coordinate swarms of small drones in environments where traditional satellite navigation is jammed or spoofed, according to a new request ...

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 ...

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 ...

The project shows a nixie clock that is accurate to a few nanoseconds a day while being synchronized with a cesium atomic clock. The project shows a nixie clock that is accurate to a few nanoseconds a ...
