  1. A concrete procedure for obtaining sharp reconstructions of unsharp observables in finite-dimensional quantum mechanics.Gianpiero Cattaneo, Tiziana Marsico, Giuseppe Nisticò & Guido Bacciagaluppi - 1997 - Foundations of Physics 27 (10):1323-1343.
    We discuss the problem of how a (commutative) generalized observable in a finite-dimensional Hilbert space (communtative effect-valued resolution of the identity) can be considered as an unsharp realization of some standard observable (projection-valued resolution of the identity). In particular, we give a concrete procedure for constructing such a standard observable. Some results about the “uniqueness” of the resulting observable are also examined.

  • On the reality of spin and helicity.Paul Busch & Franklin E. Schroeck - 1989 - Foundations of Physics 19 (7):807-872.
    The possibilities of a realistic interpretation of quantum mechanics are investigated by means of a statistical analysis of experiments performed on the simplest type of quantum systems carrying spin or helicity. To this end, fundamental experiments, some new, for measuring polarization are reviewed and (re)analyzed. Theunsharp reality of spin is essential in the interpretation of some of these experiments and represents a natural motivation for recent generalizations of quantum mechanics to a theory incorporating effect-valued measures as unsharp observables and generalized (...)
