This New Year's countdown will be one second longer as the National Physical Laboratory (NPL) introduces the 27th leap second into UTC(NPL), the UK's timescale. The additional second will keep the timescale based on atomic ...

Using their advanced atomic clock to mimic other desirable quantum systems, JILA physicists have caused atoms in a gas to behave as if they possess unusual magnetic properties long sought in harder-to-study solid materials. ...

On the wall of Aaron Dollar's office is a poster for R.U.R. (Rossum's Universal Robots), the 1920 Czech play that gave us the word "robot." The story ends with the nominal robots seizing control of the factory of their origin ...

Physicists have proposed a method for entangling hundreds of atoms, and then entangling a dozen or so groups of these hundreds of atoms, resulting in a quantum network of thousands of entangled atoms. Since small bundles ...
In the past few years, optical atomic clocks have made spectacular progress, becoming 100 times more precise than the best caesium clocks. So far, their precision has been available only locally, since frequency transfer ...
