Weak electric-field detection with sub-1 Hz resolution at radio frequencies using a Rydberg atom-based mixer
{{output}}
Rydberg atoms have been used for measuring radio-frequency (RF) electric (E)-fields due to their strong dipole moments over the frequency range of 500 MHz-1 THz. For this, electromagnetically induced transparency (EIT) within the Autler-Townes (AT) regime is u... ...
