    "abstract": "There is a commonly recognized paradigm in which a multipartite quantum\nsystem described by a density matrix having no product eigenbasis is considered\nto possess nonclassical correlation. Supporting this paradigm, we define two\nentropic measures of nonclassical correlation of a multipartite quantum system.\nOne is defined as the minimum uncertainty about a joint system after we collect\noutcomes of particular local measurements. The other is defined by taking the\nmaximum over all local systems about the minimum distance between a genuine set\nand a mimic set of eigenvalues of a reduced density matrix of a local system.\nThe latter measure is based on an artificial game to create mimic eigenvalues\nof a reduced density matrix of a local system from eigenvalues of a density\nmatrix of a global system. Numerical computation of these measures for several\nexamples is performed.",
