Scientists have taken a major step toward the ambitious global goal of “redefining the second” by the end of this decade. A ...

Quantum clocks, in particular, have pushed the boundaries by using the strange rules of quantum mechanics to achieve ...

TU Wien researchers created a quantum ring clock that achieves exponential accuracy gains with minimal energy use.

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

Now, scientists have built and tested the first prototype nuclear clock. Atomic clocks are the most accurate timekeepers we have, ... France runs fusion reactor for record 22 minutes.

That’s why the newly described clock runs on thorium, whose nucleus only requires ultraviolet light to make energy jumps. “With this first prototype, we have proven: ...

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end. According to an announcement from the National ...

Another prototype, which looks more like the Alarmo you can buy now, sat on a pedestal. “The system that serves as the brain of the alarm clock is in the base, and the LCD screen and speaker are ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of ...

By coupling a strontium atomic clock with a crystal containing thorium nuclei, ... Breakthrough: Scientists Create World's First Nuclear Clock Prototype. Story by Michelle Starr ...

A huge breakthrough decades in the making was made just a few months ago, and already scientists are realizing its potential: A measurement of the gap between the quantum energy states of a ...
