• Abstract: Using second-order perturbation theory in the light-matter interaction, we derive an analytical approximation for the vibronic populations of a diatomic system excited by ultrabroadband frequency entangled photons and evaluate the population dynamics for different degrees of entanglement between photon pairs. Our analytical approach make the same predictions as previously derived via numerical solutions of the complete Schr\"odinger equation [H. Oka, Physical Review A 97, 063859 (2018)], with the added advantage of providing clear physical insights into the vibronic selectivity as a function of the degree of photon correlations while requiring significantly reduced computational effort. Specifically, our analytical expression for the probability of vibronic excitation includes a factor which predicts the enhancement of vibrational selectivity as a function of the degree correlation between the entangled photon pairs, the targeted vibrational energy level, and the vibrational molecular structure encoded in the Franck-Condon factors. Our results illustrate the importance of going beyond the usual approximations in second-order perturbation theory to capture the relevance of the vibrational structure of the molecular system of interest in order to gain a deeper understanding of the possible quantum-enhancement provided by the interaction between quantum light and matter.

Our results put forward photon correlation asymmetry as a promising approach to investigate coherent contributions to excited-stated dynamics in molecular aggregates and other many-site quantum emitters.

  We consider a prototype light-harvesting heterodimer exhibiting coherent and collective exciton-vibration interactions. We show that coherent vibronic mechanisms strongly affect the asymmetries characteristic of time-resolved photon cross-correlations. We discuss how such second-order correlation asymmetry establishes important connections between coherent vibronic interactions, directional exciton population transport, and violation of quantum detailed balance.

  phononic excitations constitute a useful interaction channel in hybrid quantum systems. Light-scattering properties of a single-photon emitter and sidebands in resonance fluorescence spectra can be utilized for acousto-optical transduction. It is shown that the readout is faulty in situations where relevant resonant transitions are forbidden due to vanishing Franck-Condon factors.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.
