A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists ...

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 ...

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 ...
