Abstract

We design a double-slit experimental set-up, realizable at least in principle, for ascertaining three noncommuting quantum observables according to a method alternative to that of the "mean king" problem. Then, we exploit this experimental scheme to identify a physical situation where the known notions of quantum interferometry do not directly apply. A generalization of such notions is proposed that turns out to satisfy the authentic meaning of the interferometric quantum complementarity.
