Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

We propose a time–frequency resolved spectroscopic technique which employs nonlinear
interferometers to study exciton–exciton scattering in molecular aggregates. A higher degree …

Fluorescence lifetime experiments are a standard approach for measuring excited-state
dynamics and local environmental effects. Here, we show that entangled photon pairs …

We closely replicated and extended a recent experiment [Phys. Rev. Lett. 129, 183601
(2022) 0031-9007 10.1103/PhysRevLett. 129.183601] that reportedly observed …

Recent investigations have suggested that the use of non-classical states of light, such as
entangled photon pairs, may open new and exciting avenues in experimental two-photon …

We present a theoretical analysis of two-photon absorption of classical and squeezed light
valid when one-photon absorption to an intermediate state is either resonant or far-detuned …

Fluorescence excitation by absorption of entangled photon pairs offers benefits compared to
classical imaging techniques, such as the attainment of higher signal levels at low excitation …

Multiphoton absorption is of vital importance in many spectroscopic, microscopic, or
lithographic applications. However, given that it is an inherently weak process, the detection …

Resonant intermediate states have been proposed to increase the efficiency of entangled
two-photon absorption (ETPA). Although resonance-enhanced ETPA (r-ETPA) has been …

Quantum information science is driving progress in a vast number of scientific and
technological areas that cover molecular spectroscopy and matter-light interactions in …
