Abstract

It is shown that in the double-slit experiment, which is an unsharp path determination if represented by a generalized Luder operation, the interference term in the probability expression exactly corresponds to one of the marginals representing an unsharp interference observable in the realistic joint measurement presented by Busch. A complicated arrangement is presented to show a nontrivial joint triple measurement for spin-1/2 observables
