It has established a new absolute frequency value with a measurement uncertainty reduced by more than 50 times. By providing an accurate reference value for next-generation quantum technologies, this achievement is expected to contribute to the precise control and miniaturization of quantum devices, including atomic clocks and neutral-atom quantum computers.
