Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...

What if the most difficult part of keeping time wasn’t running the clock, but rather simply reading it? That counterintuitive reality has now been demonstrated on the smallest scales of quantum ...

As Make puts it, the atomic clock is old and busted. The quantum-logic clock from National Institute of Standards and Technology, keeping time 100,000 times more accurately than its predecessor, is ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

Breakthroughs in the quantum space are coming fast, and threats once dismissed as speculative now seem inevitable. For industries that rely on trust and long-lived devices, the transition to ...

This global hook-up would enable countries to synchronize timekeeping standards and improve space navigation. It could also aid the exploration of fundamental physics concepts, such as the long-sought ...

Microsemi Corporation introduced the release of its enhanced Quantum™ Rubidium Miniature Atomic Clock (MAC) SA.3X family. As one of the industry’s smallest, lightest and highest-performing MACs, the ...

Phase noise of quantum-enhanced feedback oscillators. Spectra of the output phase quadrature for four types of quantum noise-limited oscillators. Red shows the Schawlow-Townes spectrum of an ...

A Quantum World Congress Program" track, the session will explore how quantum devices' superior capabilities are opening new frontiers in medical imaging and diagnostics, environmental monitoring, ...

At this year’s LASER World of Photonics (2025), in Munich, Germany, Toptica Photonics introduced to the market what the Munich-based company describes as “the first commercially available optical ...

The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
