Charles Darwin worried that the fossil record looked strangely abrupt, with complex animals appearing in a geological instant instead of gradually unfolding over deep time. A new idea about how ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could ...

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 ...

Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...
