Description
technical field [0001] The invention belongs to the technical field of quantum detection based on atomic manipulation, in particular to a quantum power detection module. Background technique [0002] With the development of quantum technology, the quantization process of international standard units has been accelerated. The 26th International Metrology Conference in 2018 adopted a new quantization benchmark, and the kilogram, ampere, Kelvin and mole were redefined to fundamental constants, except for candela The basic units of all realize the quantization definition. Based on atomic, ion or molecular manipulation techniques, the optical atomic frequency standard has reached 10 -19 order of magnitude, and is by far the most accurate of all base units. Many other units also directly or indirectly trace the frequency through quantum technology to achieve high-precision and high-stability indicators. [0003] The quantum power detection technology based on Rydberg atoms trac...
