    "abstract": "We discuss in this letter Lewenstein-Sanpera (L-S) decomposition for a\nspecific Werner state. Compared with the optimal case, we propose a\nquasi-optimal one which in the view of concurrence leads to the same\nentanglement measure for the entangled mixed state discussed. We think that in\norder to obtain entanglement of given state the optimal L-S decomposition is\nnot necessary.",
