We present new conditions leading to the Wigner-Araki-Yanase theorem in a formulation recently proposed by Ozawa. We show that normalizable initial states and the noise operator of a detector play an important role in enabling an exact measuring process in the Heisenberg picture. Three examples clarify these ideas.

Abstract
We present new conditions leading to the Wigner-Araki-Yanase theorem in a formulation recently proposed by Ozawa. We show that normalizable initial states and the noise operator of a detector play an important role in enabling an exact measuring process in the Heisenberg picture. Three examples clarify these ideas.File in questo prodotto:
