报告摘要:
Accurate electromagnetic field sensing is of great importance and necessity for exploring new materials, developing electronic devices and investigating electromagnetic effects. Ideally, radio-frequency (RF) field measurements should be directly linked to SI units with low intrusion, high sensitivity, wide dynamic range and low uncertainty. The current state-of-the art is far short of this goal. It has been proved that quantum coherence effects in highly-excited Rydberg atoms could provide a revolutionary solution for RF field measurement,the field strength can be directly linked to the measured Autler-Townes (AT) splitting and Planck’s constant. Some recent progress and interesting applications will be presented, including the development of self-traceable quantum RF E-field and power standards, atomic communication. The measurement uncertainty evaluation and the main measurement error effects will be discussed as well.
