Nonlinear spectroscopy with nonclassical light — •Fabiano Lever and Markus Ghuer — Universitaet Potsdam

In this work, we explore the quantum-classical transition comparing a classical pump-probe experiment on a diatomic molecule to its quantum enhanced counterpart, where the pump and probe pulses are substitued by the signal and idler beams of a SPDC source.

Two photon absoption of biphotons generated with Spontaneous Parametric Down Conversion (SPDC) exploits quantum time-energy correlations to enhance the overall yeld and selectivity of the process, when compared with a classical pump-probe setup, while mantaining femtosecond time resolution. The results indicate that the quantum improvements in yeld are caused by a more efficient use of the total power available for the process.
