Making Sense of Approximate Decoherence

Guido Bacciagaluppi, Meir Hemmo

Research output: Contribution to journalArticlepeer-review


[In realistic situations where a macroscopic system interacts with an external environment, decoherence of the quantum state, as derived in the decoherence approach, is only approximate. We argue that this can still give rise to facts, provided that during the decoherence process states that are, respectively, always close to eigenvectors of pointer position and record observable are correlated. We show in a model that this is always the case.]
