Ensuring that different clocks are giving the same time is crucial to enable electronic systems to talk to each other. But what is the cost of this synchronisation at the thermodynamic level? To ...

The first clock measures how fast AI capabilities are improving. New advances arrive from labs, vendors and the research community—and move on whether you’re ready or not. The forces driving this ...

Historically, JILA (a joint institute established by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) has been a world leader in precision timekeeping ...

Comparing Clock to Clock A key innovation in this study was directly comparing the two atomic sub-ensembles. Thanks to the vertical lattice, the researchers could switch which atomic sub-ensembles ...
