We discuss the role played by the decoherence parameter in the many-Hilbert-space approach to quantum measurements. Some criticisms recently put forward by de Muynck and Martens are analyzed, countered and shown to be flawed. It is clarified that a nonvanishing value of the decoherence parameter represents an irreversible loss of quantum-mechanical coherence.

Abstract
We discuss the role played by the decoherence parameter in the many-Hilbert-space approach to quantum measurements. Some criticisms recently put forward by de Muynck and Martens are analyzed, countered and shown to be flawed. It is clarified that a nonvanishing value of the decoherence parameter represents an irreversible loss of quantum-mechanical coherence.File in questo prodotto:
