Title :Generalized states and measuring processes for continuous observables
Authors :Matsumoto, Shuichi
Authors alternative :松本, 修一
Issue Date :25-Feb-1993
Abstract :An extension of the concept of physical state is introduced. It is shown that if we accept all the "generalized states" as initial states of an apparatus, then we can circumvent the Ozawa's theorem which rules out the existence of repeatable measuring processes for continuous observables. A generalization of the Wigner-Araki- Yanase theorem is argued.
