Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

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 ...
