Quantum Assisted Sensing Using Rydberg Atom Electromagnetically Induced Transparency

POSTER

Abstract

We present a method to probe AC electric fields with high sensitivity based on dark resonances in electromagnetically induced transparency (EIT) spectroscopy. The basic mechanism is to couple the electric field to a ladder-type Rydberg atom EIT system. Data from experiments using Cs and Rb will be shown to illustrate the method. The experiments take place in small (mm-$\mu $m) vapor cells. We discuss our experiments to push the electric field sensitivity of the method below 1$\mu $V/cm.
