Quantum-enhanced two-photon spectroscopy using two-mode squeezed light

Abstract

We investigate the prospects of using two-mode intensity squeezed twin beams, generated in Rb vapor, to improve the sensitivity of spectroscopic measurements by engaging two-photon Raman transitions. As a proof-of-principle demonstration, we recorded quantum-enhanced measurements of the Rb5D3/2hyperfine structure with reduced requirements for the Raman pump laser power and Rb vapor number density.
