Caducity of Idea about Wave Function Collapse    [PDF]

Spiridon Dumitru

Investigated idea was incited by the conflicting hypotheses : (i) the old opinion that for a quantum observable a measurement should be regarded as a single deterministic sampling and (ii) the agreement about probabilistic character of the wave function marking the system to which observable refers. For avoiding the conflict it was suggested to depict the alluded measurement through a collapse of the respective wave function into a particular eigenfunction of that observable. But, the last decades studies point out a true character of random variables for quantum observables. Or an useful measurement for such an observable must imply a significant set of statistical samplings. So one finds the indubitable caducity of the idea in question. Contiguously the quantum mechanics theory must be regarded either in restricted or in extended reading, as it refers to the studied systems without or with taking into account the description of measurements. The above views are adaptable to some simple situations illustrated in the end of article.
