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 ...

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

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

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 ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

The fragility and laws of quantum physics generally make the characterisation of quantum systems time-consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A ...

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 ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can ...

For the first time in Cougar history, Brigham Young University students competed in the Massachusetts Institute of Technology's annual quantum hackathon from Jan. 30 to Feb. 1 — and won.
