- Abstract: We investigate optimal states of photon pairs to excite a target transition
in a multilevel quantum system. With the help of coherent control theory for
two-photon absorption with quantum light, we infer the maximal population
achievable by optimal entangled vs. separable states of light. Interference
between excitation pathways, as well as the presence of nearby states, may
hamper the selective excitation of a particular target state, but we show that
quantum correlations can help to overcome this problem, and enhance the
achievable "selectivity" between two energy levels, i.e. the relative
difference in population transferred into each of them. We find that the added
value of optimal entangled states of light increases with broadening linewidths
of the target states.

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.

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.
