The physicist Jian Wei Pan and his colleagues have achieved an important milestone in redefining the second, as they found a way to synchronize the timing of two clocks remotely with exceptional precision using air, over a record distance of 113 kilometers.
Description
The Chinese team managed to achieve a significant breakthrough in the field of time synchronization, successfully synchronizing the timing of two clocks with exceptional precision over a distance of 113 kilometers using lasers. This achievement is a significant step towards redefining the second and improving the accuracy of timekeeping devices.
