EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the ...

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

The “minute” on your phone is not a natural thing. Nothing in the sky divides an hour into 60 equal parts. Humans invented ...

A team of scientists at King’s College London has discovered a new set of mathematical equations that can turn any sequence of random, unpredictable events into a clock. This research suggests that ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range ...

Scientists have developed a novel interferometric technique capable of measuring time delays with zeptosecond (a trillionth of a billionth of a second) resolution. They have used this technique to ...
