Abstract: We introduce a potential of multipartite entanglement for a system of nqubits, as the average over all balanced bipartitions of a bipartiteentanglement measure, the purity. We study in detail its expression and lookfor its minimizers, the maximally multipartite entangled states. They have abipartite entanglement that does not depend on the bipartition and is maximalfor all possible bipartitions. We investigate their structure and considerseveral examples for small n.
