MAXIMALLY MULTIPARTITE ENTANGLED STATES

The characterization of multipartite entanglement is a central problem in quantum information and many-body systems theory. We introduce
 the notion of maximally multipartite entangled states of n qubits as a generalization of the bipartite case. These pure states have a bipartite
 entanglement that does not depend on the bipartition and is maximal for all possible bipartitions. They are solutions of a minimization problem.
 Examples for small n are investigated, both analytically and numerically via deterministic and stochastic algorithms.
