    "abstract": "We introduce an operational procedure to determine, with arbitrary\nprobability and accuracy, optimal entanglement witness for every multipartite\nentangled state. This method provides an operational criterion for separability\nwhich is asymptotically necessary and sufficient. Our results are also\ngeneralized to detect all different types of multipartite entanglement.",
