Title: Overcoming the Classical limits of ultRafast spEctroSCopy with ENtangleD phOtons.

ICCOM Principal Investigator: Fabrizio Santoro.

Project Type: National.

Duration: 28/09/2023 – 27/09/2025.

Abstract: Many research actions are focussing on the possible exploitation of properties of single quantum objects, like state superposition and entanglement, to achieve the so called “quantum advantage”, like for applications in quantum computing. Recently, a growing body of theoretical studies has proposed to use quantum states of light, such as squeezed states or entangled photon pairs (EPPs), to enhance also ultrafast optical spectroscopy; however experimental demonstrations of nonlinear spectroscopy with quantum light are very limited. CRESCENDO has created a multidisciplinary experimental and computational team with the aim to replace the classical probes in ultrafast spectroscopy with EPPs and experimentally demonstrate the “quantum advantage” in terms of sensitivity and novel spectroscopic signals for the study of molecular systems and aggregates. As a model system we choose dimers and oligomers of Zinc-Phthalocyanine, an important category of porphyrin dyes with unique optical, magnetic and electronic properties.
