摘要 

In this talk, I will present our recent achievement in the quest ofelectromagnetic-wave quantum sensors that simultaneously offer super-high sensitivity, SI-traceability, and phase resolutions. In particular, we have developed a conceptually new microwave sensor based on microwave-dressed Rydberg atoms and engineered optical spectrum [1]. This new sensor scales favorably,making the minimum detectable microwave field three orders of magnitude smaller than what can be reached by existing atomic electrometers. It enables SI-traceable measurements, reaching uncertainty levels that have been inaccessible so far with atomic sensors. It moreover enables a high precision in sensing Doppler frequencies. This innovative sensing technique will benefit a wide range of fields such as quantum simulation, quantum metrology, and radio astronomy.
