  Recent results in quantum information theory characterize quantum coherence
in the context of resource theories. Here we study the relation between quantum
coherence and quantum discord, a kind of quantum correlation which appears even
in non-entangled states. We prove that the creation of quantum discord with
multipartite incoherent operations is bounded by the amount of quantum
coherence consumed in its subsystems during the process. We show how the
interplay between quantum coherence consumption and creation of quantum discord
works in the preparation of multipartite quantum correlated states and in the
model of deterministic quantum computation with one qubit.
