    "abstract": "The problem of the experimental determination of the amount of entanglement\nof a bipartite pure state is addressed. We show that measuring a single\nobservable does not suffice to determine the entanglement of a given unknown\npure state of two particles. Possible minimal local measuring strategies are\ndiscussed and a comparison is made on the basis of their best achievable\nprecision.",
