Monotonic measures of quantum correlations

We perform a systematic search for new measures of bipartite quantum correlation. We require monotonicity so that our quantities may be identified as information. Several types of monotonicity are defined, and enforced by requiring quantities to satisfy particular pairs of inequalities which we derive. We find three measures of correlation, one of which is the entanglement of purification, the other two have not been thoroughly studied. We hope to eventually find geometric interpretations for these quantities in the context of holography, since such an interpretation already exists for the entanglement of purification.
