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 ...

New research has revealed another set of tasks most humans can do with ease that artificial intelligence (AI) stumbles over — reading an analogue clock or figuring out the day on which a date will ...

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

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...

These days, artificial intelligence can generate photorealistic images, write novels, do your homework, and even predict protein structures. New research, however, reveals that it often fails at a ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Facepalm: Generative AI tools are able to perform the sorts of tasks that once seemed the stuff of sci-fi, but most of them still struggle with many basic skills, including reading analog clocks and ...

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 ...
