The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

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 ...

David Gozzard is in the International Centre for Radio Astronomy Research and Department of Physics, University of Western Australia, Crawley 6009, Australia. Atomic clocks keep time using the ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

From left to right, Adam Kaufman, Nelson Darkwah Oppong, Alec Cao and Theo Lukin Yelin inspect an atomic optical clock at JILA. Imagine walking into a room where several different grandfather clocks ...

The first-ever deployment of a quantum optical atomic clock on an underwater autonomous submarine has been successfully completed. Infleqtion’s Tiqker optical atomic clock was integrated into the ...

Established as a provider of high-end lasers and laser rack systems, Toptica has this week announced at LASER world of Photonics that is offering its first complete quantum technology solution: a ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...
