- 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 demonstrated the quantum-enhanced measurements of the Rb
$5D_{3/2}$ hyperfine structure with reduced requirements for the Raman pump
laser power and Rb vapor number density.

We investigated the fluorescence signals from Rhodamine 6G and LDS798 excited with a CW laser or an entangled photon pair source at 1060 nm.
We observed a signal that originates from hot-band absorption (HBA), which is one-photon absorption from thermally-populated vibrational levels of the ground electronic state.
For the typical conditions under which E2PEF measurements are performed, contributions from the HBA process could lead to a several orders-of-magnitude overestimate of the quantum advantage for excitation efficiency.
