Probing quantum correlations in molecular systems with polarization-entangled photons

Quantum-light can be a powerful tool for the field of molecular spectroscopy. We develop a theoretical framework to treat scattering of quantum photons by open quantum systems and use quantum process tomography to describe the interactions of polarization-entangled biphoton states with molecular systems. Using this theory, we compare what can be learned from single or multiple photon-scattering events of polarization entangled photons with what can be learned about quantum correlations in molecular systems using existing multidimensional electronic spectroscopies.
