In quantum mechanics, the consistent histories or simply "consistent quantum theory"[1] interpretation generalizes the complementarity aspect of the conventional Copenhagen interpretation. The approach is sometimes called decoherent histories[2] and in other work decoherent histories are more specialized.[1]
First proposed by Robert Griffiths in 1984,[3][4] this interpretation of quantum mechanics is based on a consistency criterion that then allows probabilities to be assigned to various alternative histories of a system such that the probabilities for each history obey the rules of classical probability while being consistent with the Schrödinger equation. In contrast to some interpretations of quantum mechanics, the framework does not include "wavefunction collapse" as a relevant description of any physical process, and emphasizes that measurement theory is not a fundamental ingredient of quantum mechanics. Consistent Histories allows predictions related to the state of the universe needed for quantum cosmology.[5]
