Entangled Two-Photon Absorption: New Opportunities in Molecular Science and Spectroscopy

Two-photon absorption techniques have long been used to extract information about the dynamics and structure of complex systems. Even though in the optical regime two-photon absorption is typically implemented using laser light, recent investigations suggest that the use of non-classical states of light, such as entangled photon pairs, may open new and exciting avenues in experimental molecular science and spectroscopy. In this special symposium, research groups at the forefront of theory and experimental work on entangled two-photon absorption will present their latest results, with the aim at recognizing the true quantum-advantage that this effect might offer to the development of novel materials and spectroscopy techniques. The goal of this special session is not only to highlight this emerging exciting field, but to establish a platform for exchanging ideas and foster research and innovation in entangled-light-matter interaction applications.
