Many tasks in quantum information require the preparation of multipartite entangled states. The number of local measurements one needs to determine complete information about a quantum system grows exponentially with the number of particles. Thus in all practical scenarios one is faced with the challenge of revealing as many desirable properties of a state as needed with as few local measurements as possible. We show that using a framework of nonlinear entanglement witnesses one can lower bound measures of genuine multipartite entanglement in an optimal way and furthermore reveal the structure of genuinely multidimensional features of multipartite quantum systems.
