Abstract: The paper describes a solution to the problem of quantum measurement that hasbeen proposed recently. The literal understanding of the basic rule of quantummechanics on identical particles violates the cluster separation principle andso leads to difficulties. A proposal due to Peres of how such difficultiescould be removed is reformulated and extended. Cluster separability leads to alocality requirement on observables and to the key notion of separation status.Separation status of a microsystem is shown to change in preparation andregistration processes. The indispensability of detectors plays an importantrole. Changes of separation status are alterations of kinematic descriptionrather than some parts of dynamical trajectories and so more radical than-collapse of the wave function-. Textbook quantum mechanics does not provideany information of how separation status changes run, hence new rules must beformulated. This enables to satisfy the objectification requirement forregistrations. To show how the ideas work, a simplified model of registrationapparatus is constructed.
