A recent study has unveiled a surprising revelation about quantum timekeeping: the energy required to read a quantum clock surpasses the energy needed to keep it running. This discovery, published on ...

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 ...

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 ...
