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