Perfect timekeeping is more complicated than you think. Most clocks slow down over time (not that many people notice), and tiny imperfections in the manufacturing process ensure that no two timepieces ...

Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

For the first time in the history of optical atomic clocks, a government agency is not funding a better demonstration — it is funding a manufacturing line. DARPA awarded IonQ (NYSE: IONQ) a $28 ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...
