Voltage and power-frequency electric field measurements with Rydberg-atom interferometry
Yingying Han, Changfa He, Zhenxiong Weng +3
We present a Rydberg-atom interferometry-based technique for voltage measurement between electrodes embedded in an atomic vapor cell, enabling the detection of weak voltages ($<0.1…
