More specifically we focus on Tsallis and Renyi entropic uncertainty relations and we get that the minimum joint uncertainty states for some fluctuation measures are the maximum joint uncertainty states of other fluctuation measures, and vice versa.engEffect of fluctuation measures on the uncertainty relations between two observables: different measures lead to opposite conclusionsjournal articlehttp://dx.doi.org/10.1103/PhysRevA.84.034101http://journals.aps.org/open access535Entropic uncertaintyQuantum measurementsPhase measurementComplementary observablesOptical-phaseInformationMechanicsPrincipleStandardAngleÓptica (Física)2209.19 Óptica Física
