While AI grabs headlines, quantum computing quietly threatens to upend digital security foundations.

Add Yahoo as a preferred source to see more of our stories on Google. For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum ...

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 technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

A device that relies on quantum effects and oversized atoms may be a more reliable way to measure temperature that doesn't ...

Researchers have proposed that imperfect timekeeping inside quantum processors can create a fundamental noise channel that ...

Keeping track of time seems simple. A watch ticks, a pendulum swings, and a calendar flips. But at the quantum level, marking time is far more complicated — and far more expensive than anyone expected ...

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 ...
