    "abstract": "We show that, for any composite system with an arbitrary number of\nfinite-dimensional subsystems, it is possible to directly measure the\nmultipartite concurrence of pure states by detecting only one single\nfactorizable observable, provided that two copies of the composite state are\navailable. This result can be immediately put into practice in trapped-ion and\nentangled-photon experiments.",
