    "abstract": "We present an extension of the Wootters concurrence for the case of two\nqutrits in mixed states. The reduction of our extension to the case of two\nlevels shows complete agreement with Wootters concurrence for two qubits. As an\nexplicit example, we compute the concurrence for a family of symmetric states\nand we obtain the bounds on the limit for separability. Our results are\ncompared with those of the negativity.",
