Negativity and Concurrence as complete entanglement measures for two arbitrary qudits
Suranjana Rai, Jagdish R. Luthra
Two measures of entanglement, negativity and concurrence are studied for two arbitrary qudits. We obtain negativity as an expectation value of an operator. The differences of the s…

Negativity and Concurrence for two qutrits
Suranjana Rai, Jagdish R. Luthra
Two measures of entanglement, negativity and concurrence are studied for two qutrits. An operator origin of negativity is presented and an analytic formula connecting the two measu…

Generalized concurrence and limits of separability for two qutrits
César Herreño-Fierro, J. R. Luthra
We present an extension of the Wootters concurrence for the case of two qutrits in mixed states. The reduction of our extension to the case of two levels shows complete agreement w…
