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

While standard quartz clocks are pretty reliable when it comes to their measurement of time on Earth, they do suffer from a problem with “drift.” In other words, over time these clocks become ...
