A chip that keeps time (almost) like an atomic clock
For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...
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 ...
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 ...
