These relations fully explain the enforcement of complementarity in situations in which the standard position-momentum uncertainty relation plays no role.engComplementarity and certainty relations for two-dimensional systemsjournal articlehttp://dx.doi.org/10.1103/PhysRevA.64.012103http://journals.aps.org/open access535Classical phase kicksWelcher weg measurementsWhich-way informationWave-particle dualityUncertainty relationQuantum-mechanicsNeutron interferometryAtom interferometerDifference operatorFringe visibilityÓptica (Física)2209.19 Óptica Física
