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 ...

The clock network of the fruit fly Drosophila melanogaster (gray). The clock neurons of the core clock, which form the minimal circuit of the internal clock, are highlighted in color. The four dorsal ...

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 ...
