Theoretical analysis of an electrometer based on microwave-dressed Rydberg atoms using a quantum interferometer

Rydberg atoms have demonstrated exceptional capabilities in the precise sensing microwave (MW) fields. Previous studies on Rydberg atom-based electrometers (RAEs) have predominantly focused on absorption measurements. Recently, phase-sensitive RAEs employing Mach-Zehnder interferometer (MZI) have been demonstrated, though their performance remains constrained by the standard quantum limit (SQL). In this study, we combine RAEs with advanced quantum interferometrics to enhance MW field sensing. Within the framework of electromagnetically induced transparency (EIT) and Autler-Townes (AT) splitting, the noise of our enhanced electrometer is suppressed below the photon shot noise (PSN) in measuring light dispersion through microwave-dressed atoms, when utilizing phase squeezed states. In our theory, the optimal sensitivity of the MW field can reach 1.36 × 10 −11 V/m/Hz 1/2 with a dressed MW field strength of 2.4 × 10 −4 V/m within a balanced SU(1,1) interferometer.

Dispersion readout of micro-wave electric field using double-dark-state Rydberg atoms

Aihong Yang, Yandong Peng, Yan Xu +1 more

Abstract A dispersion probe of the electric fields of microwaves (MWs) is proposed using double-dark-state Rydberg atoms with Doppler effects. The MW field splits the atomic absorption spectrum, with normal dispersion at the central frequency. We investigate the sensitivity of the dispersion to the MW field strength. The numerical result reveals a linear relationship between the phase shift induced by the dispersion and the MW field intensity, which can be used to estimate MW electric field strength. Doppler effects can enhance the dispersion and greatly improve the measurement sensitivity. Our simulations show the probe sensitivity increases more than 10 times after Doppler averaging.
