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

Active research on halide perovskites has given us a deep understanding of this family of
materials and their potential for applications in advanced optoelectronic devices. One of the …

When a low flux of time-frequency-entangled photon pairs (EPP) illuminates a two-photon
transition, the rate of two-photon absorption (TPA) can be enhanced considerably by the …

Multiphoton absorption of entangled photons offers ways for obtaining unique information
about chemical and biological processes. Measurements with entangled photons may …

Two-photon absorption (TPA) and other nonlinear interactions of molecules with time–
frequency-entangled photon pairs have been predicted to display a variety of fascinating …

It has been proposed that entangled two-photon absorption (E2PA) can be observed with up
to 1010 lower photon flux than its classical counterpart, therefore enabling ultralow-power …

The dependence of the polymerization and optical damage thresholds in multi-photon
polymerization (MPP) lithography was studied using a broadly-tunable laser system with …

We experimentally study entangled two-photon absorption in rhodamine 6G as a function of
the spatial properties of a high flux of broadband entangled photon pairs. We first …

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

Entangled two-photon absorption (ETPA) has recently become a topic of lively debate,
mainly due to the apparent inconsistencies in the experimentally reported ETPA cross …
