Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

The study shows that in quantum devices, reading a clock consumes far more energy than running it. This insight will help ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

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 ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist thanks to new research led by physicists at École Polytechnique Fédérale ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

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 ...

Breakthrough trial with Tiqker clock aboard XCal submarine advances resilient navigation in GPS-denied environments Testbed submarine XV Excalibur went to sea with Infleqtion’s quantum optical atomic ...

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...
