    "abstract": "The present methods for obtaining the optimal Lewenestein- Sanpera\ndecomposition of a mixed state are difficult to handle analytically. We provide\na simple analytical expression for the optimal Lewenstein-Sanpera decomposition\nby using semidefinite programming. Specially, we obtain the optimal\nLewenstein-Sanpera decomposition for some examples such as: Bell decomposable\nstate, Iso-concurrence state, generic two qubit state in Wootters\u0027s basis,\n$2\\otimes 3$ Bell decomposable state, $d\\otimes d$ Werner and isotropic states,\na one parameter $3\\otimes 3$ state and finally multi partite isotropic state.",
