We introduce a method for the study of [ital CP]-violating asymmetries in tagged states of neutral [ital B] mesons with arbitrary coherence properties. A set of time-dependent measurements is identified which completely specifies the density matrix of the initial state in a two-component space with basis vectors [ital B][sup 0] and [ital [bar B]] [sup 0], and permits a determination of phases in the Cabibbo-Kobayashi-Maskawa matrix. For a given tagging configuration, the measurement of decays both to flavor eigenstates and to [ital CP] eigenstates provides the necessary information.
