%0 Journal Article %A Luis Aina, Alfredo %T Operational approach to complementarity and duality relations %D 2004 %@ 1050-2947 %U https://hdl.handle.net/20.500.14352/51506 %X We present a fully operational and consistent approach to complementarity. In contrast to previous approaches, in this proposal the duality relations emerge exclusively from the outcomes of simultaneous measurements performed on every run of the experiment and under the same experimental conditions. This can be done without assuming any definite relationship between the measurement performed and the complementary observables being studied. %~
