The Consistent Histories Interpretation as a Solution to the Quantum Measurement Problem

This thesis considers the quantum measurement problem, the problem of representing definite measurement outcomes in the formalism of quantum mechanics. I evaluate the consistent histories interpretation as a solution to the problem, comparing its merits and deficiencies to those of the standard interpretation of quantum mechanics. The single-framework rule, a key principle of the consistent histories interpretation, is intertwined with the issue of whether the consistent histories interpretation solves the measurement problem. By arguing for a specific clarification of the rule, I show that the consistent histories interpretation does indeed solve the problem. The consistent histories interpretation is more rigorous and general than the standard interpretation. However, it provides a flawed metaphysical picture by treating measuring apparatuses as a fundamentally different type of entity than ordinary objects.
