A recent design created using entangled atoms to keep time could benefit scientists detect dark matter, a gravity’s effect on time.

The most precise timekeepers in the world are atomic clocks which use lasers to measure the vibration of atoms that swing at a constant frequency.

This new kind of atomic clock designed by MIT physicists may enable scientists to explore questions related to new physics as well as get answers to intriguing concepts for example time change as the universe ages. Aren’t you curious about such fascinating theories ?

Researchers report that they have built an atomic clock that measures not a cloud of randomly oscillating atoms, as today, but instead atoms that have been quantumly entangled. The atoms are connected in a way that is impossible according to the laws of classical physics, and that allows the scientists to measure the vibrations of atoms accurately.

If today’s modern atomic clocks were adapted to measure entangled atoms the way the MIT team’s setup does, their timing would improve such that, over the entire age of the universe, the clocks would be less than 100 milliseconds off! Woah, that’s captivating
