The<a href=\"https:\/\/physics.nist.gov\/cuu\/Units\/index.html\"> International System of Units<\/a> (SI) define a second as a certain number of oscillations of the atom caesium and atomic clocks govern many of the technologies that we live with an use on a daily basis: The internet, satellite navigation, air traffic control and traffic lights to name but a few.<\/p>\n<p>However, recent developments in optical quantum clocks that use single atoms of metals like aluminium or strontium are thousands of times more accurate than traditional atomic clocks. To put this in perspective, the best caesium atomic clock as used by institutes like NIST (National Institute for Standards and Time) or NPL (National Physical Laboratory) to govern the world\u2019s global timescale <a href=\"https:\/\/en.wikipedia.org\/wiki\/Coordinated_Universal_Time\">UTC<\/a> (Coordinated Universal Time), is accurate to within a second every 100 million years.
