Clocks are essential building blocks of modern technology, from computers to GPS receivers. They are also essentially engines, irreversibly consuming resources in order to generate accurate ticks. But what resources have to be expended to achieve a desired accuracy? In our latest study, published in Physical Review X, we answer this question by measuring, for the first time, the entropy generated by a minimal clock.
