A typical atomic clock works by measuring the vibrations on the atomic stage of cesium-133 atoms, which oscillate with absolute consistency, 9,192,631,770 occasions a second. Historically, lasers measure a cloud of those randomly oscillating, cooled-down cesium-133 atoms. MIT’s new clock, nonetheless, makes use of ytterbium atoms which have been entangled, that means the atoms behave in a uniform vogue, with the atoms oscillating in sync quite than randomly. Ytterbium’s oscillation fee is 100,000 items quicker per second than cesium-133, and these oscillations could be tracked extra exactly, permitting the workforce to measure even smaller intervals of time. In different phrases, they’ve achieved elevated accuracy.
