New type of atomic clock keeps time even more precisely December 19, 2020MIT The design, which uses entangled atoms, could help scientists detect dark matter and study gravity’s effect on time. Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning of the universe, they would only be off by about half a second today. ....
A new kind of atomic clock possibly reveal new physics The design, which uses entangled atoms, could help scientists detect dark matter and study gravity’s effect on time. Atoms are trapped in an optical cavity composed of two mirrors. When a “squeezing” laser is set through the cavity, the atoms are entangled, and their frequency is measured with a second laser, as a platform for more precise atomic clocks. Credits: MIT scientists MIT scientists have designed a new kind of atomic clock that could answer some mind-boggling questions, such as what effect gravity might have on the passage of time and whether time itself changes as the universe ages. ....

If left to run for some 14 billion years roughly the current age of the universe a new type of atomic clock could keep accurate time to within a tenth of a second. The design by US experts makes use of a bizarre phenomenon called quantum entanglements, in which particles become inextricably linked. This entanglement, the researchers explained, helps reduce the uncertainty involved in measuring the oscillation of atoms used by atomic clocks to keep time. The clock could be used to help reveal the elusive dark matter thought to make up more than three-quarters of the universe and to study gravity s effect on time. ....
The design, which uses atoms entangled at the quantum level, could also allow scientists to detect dark matter and study gravity’s effect on time. (CN) Researchers announced the creation of a new type of superaccurate atomic clock that could be capable of measuring undiscovered cosmic phenomena like dark matter and the effect gravity can have on time itself. Humans throughout history have relied on natural occurrences and manmade instruments to gauge the passing of time. From the ancient Egyptian sundials that tracked the sun’s progress through the sky to battery-powered wristwatches of the modern era, humans have utilized numerous inventive methods to measure and define our journey through time. ....
