  "abstract": "Recently, it was argued that the binegativity might be a good measure of entanglement for two-qubit states. We prove that it is convex in quantum states and might be a LOCC monotone as well thus fulfills the criterion to be a good measure of entanglement. Then we investigate its behavior under noisy channels which supports our claim. Our results indicate that the binegativity might play an important role in the resource theory of entanglement.",
