  Entanglement is one of the most studied properties of quantum mechanics for
its application in quantum information protocols. Nevertheless, detecting the
presence of entanglement in large multipartite sates continues to be a great
challenge both from the theoretical and the experimental point of view. Most of
the known methods either have computational costs that scale inefficiently with
the number of particles or require more information on the state than what is
attainable in everyday experiments. We introduce a new technique for
entanglement detection that provides several important advantages in these
respects. First, it scales efficiently with the number of particles, thus
allowing for application to systems composed by up to few tens of particles.
Second, it needs only the knowledge of a subset of all possible measurements on
the state, therefore being apt for experimental implementation. Moreover, since
it is based on the detection of nonlocality, our method is device independent.
We report several examples of its implementation for well-known multipartite
states, showing that the introduced technique has a promising range of
applications.
