Generalizing the quantifiers used to classify the nature of correlations in bipartite systems, I introduce a definition for genuine total, quantum, and classical correlations for states of three qubits. The measure is based on the use of relative entropy to quantify the “distance'' between two density matrices. I shall show that, for pure tripartite states, both quantum and classical bipartite correlations obey a ladder ordering law fixed by two-body mutual informations, or, equivalently, by one-qubit entropies.
