    "abstract": "We propose a simple geometrical approach for finding the robustness of\nentanglement for Bell decomposable states of 2 otimes 2 quantum systems. It is\nshown that the robustness of entanglement is equal to the concurrence. We also\npresent an analytical expression for two separable states that wipe out all\nentanglement of these states. Finally the random robustness of these states is\nalso obtained.",
