Abstract

 

We propose a method to characterize and quantify multipartite  entanglement for pure states. The method hinges upon the study of    the probability density function of bipartite entanglement and is    tested on an ensemble of qubits in a variety of situations. As a further testground, we apply this characterization to the finite size Ising model with a transverse field and study its entanglement properties.
