Markovian dynamics of single-rebit open quantum systems with applications to colour perception
Michel Berthier, Gabriel Niebel, Edoardo Provenzi
This paper investigates the Markovian dynamics of open two-state quantum systems defined over the real numbers (rebits). Two main objectives are pursued. First, we present a compre…
An Operational Quantum Information Framework for Experimental Studies on Color Perception
Roberto Leporini, Edoardo Provenzi, Michel Berthier
Starting from the foundational axiomatization of the perceptual color space initiated by Schrödinger in 1920 and eventually refined by Resnikoff in 1974, Berthier, Provenzi and th…
The classification of rebit quantum channels
Michele Aldé, Michel Berthier, Edoardo Provenzi
The classification of qubit channels is known since 2002. However, that of rebit channels has never been studied so far, maybe because of the scarcity of concrete rebit examples. I…
Split-quaternions for perceptual white balance
Michel Berthier, Nicoletta Prencipe, Edoardo Provenzi
We propose a perceptual chromatic adaptation transform for white balance that makes use of split-quaternions. The novelty of the present work, which is motivated by a recently deve…
Quantum measurement and color perception: theory and applications
Michel Berthier, Edoardo Provenzi
In this paper we make a systematic use of the quantum measurement theory to describe perceived colors and analyze some of their fundamental properties. After motivating the natural…
