Measurement quantum mechanics and experiments on quantum Zeno effect

Abstract

Measurement quantum mechanics, the theory of a quantum system which undergoes a measurement process, is introduced by a loop of mathematical equivalencies connecting previously proposed approaches. The unique phenomenological parameter of the theory is linked to the physical properties of an informational environment acting as a measurement apparatus which allows for an objective role of the observer. Comparison with a recently reported experiment suggests how to investigate novel interesting regimes for the quantum Zeno effect.Comment: 18 pages RevTeX, 2 postscript figures included with PSFIG, uuencoded gz-compressed .tar file; to be published in Annals of Physic
