Recently, the National Institute of standards and Technology (NIST) physicists wrote in science express that a pair of ytterbium atomic clock test devices developed by NIST created a new record of atomic clock stability

the bending strength reaches 50 times. The so-called stability refers to the degree of difference between the timing cycles of the timing device. If the ytterbium atomic clock is regarded as a swinging pendulum or metronome, accurate timing since the birth of the universe can be achieved

according to the physicist who developed the device, the stability of the timing cycle of the ytterbium atomic clock can reach 1/500 billion, which is at least 10 times higher than the published existing atomic clock timing device. Experts said that this technological breakthrough will not only greatly improve the accuracy of people's timing, but also have a broad application space in the precise sensing measurement of gravity field, magnetic field, temperature and so on
