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 ...
Some New York City schools banned phones to improve focus, but the move revealed a new issue. Many students have forgotten ...
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 ...
They just forgot that skill because they never used it, because they always pulled out their phone,” said Cheyenne Francis, ...
Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...
If you can read a traditional analog clock then congratulations, you’re smarter than artificial intelligence. AI is proving to be good at a lot of things, but reading an old-fashioned clock is not one ...
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 ...
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 ...
