Abstract
We theoretically investigate two-photon excitation by correlated photons with energy anticorrelation. A three-level atomic system is used to evaluate selectivity and efficiency of two-photon excitation. It is shown that tailored squeezing of two-photon probability distribution concurrently enhances excitation efficiency and high-contrast selective excitation, without phase manipulation or pulse-shaping techniques. We also discuss candidates to generate such squeezed photons in real material systems.
