The Korea Research Institute of Standards and Science (KRISS) has remeasured a key transition frequency of the strontium (Sr) atom for the first time in 88 years, since 1938, using a photonic grating chip. 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. The work is published in the journal Metrologia.
