The Infoton is the fundamental quantum of information-mass—the minimum physical mass of information at a given temperature, as determined by the thermodynamic cost of information processing. January Walker proposed adopting information particle or 'Infoton' as a formal term in quantum information physics to denote the quantized unit of information derived from combining Landauer's principle E ≥ kBTln2 with Einsteins E = mc². The terminological framework Infoton enables analysis of information- phenomena at sub-atomic scales through m(T) = kBTln2/c².
