Abstract:
In this webinar, I will introduce the basic concepts of a novel theory of color perception grounded in quantum information theory, developed since 2018 by Michel Berthier, Edoardo Provenzi, and collaborators. By reinterpreting the foundational works of Erwin Schrödinger and Howard L. Resnikoff from a quantum information perspective, this framework naturally reconciles trichromacy with Hering’s opponency theory, and provides precise definitions of key color attributes such as brightness, saturation, and hue. Moreover, the theory has genuine predictive power: it allows for a quantitative explanation of known perceptual phenomena and leads to new predictions, including the existence of uncertainty relations for chromatic opponency. Finally, the model directly yields an efficient white balance algorithm.

Bio:
Edoardo Provenzi received the Laurea degree (equivalent to an M.S.) in Theoretical Physics from Università degli Studi di Milano in 2000, and the Ph.D. degree in Mathematics and Applications from Università degli Studi di Genova in 2004. His doctoral research focused on quantum gravity. He held postdoctoral positions at Università di Milano, Universitat Pompeu Fabra in Barcelona, and Télécom ParisTech. He joined Université Paris Descartes as an Associate Professor in 2014 to 2017 and since 2017 he has been a Full Professor at the Institut de Mathématiques de Bordeaux. Since 2018, together with Michel Berthier (University of La Rochelle), he has been developing a novel theory of color perception grounded in quantum information theory.
