Abstract
We employ conditional Tsallis q entropies to study the separability of symmetric one parameter W and GHZ multiqubit mixed states. The strongest limitation on separability is realized in the limit q-->infinity, and is found to be much superior to the condition obtained using the von Neumann conditional entropy q=1 case. Except for the example of two qubit and three qubit symmetric states of GHZ family, the q-conditional entropy method leads to sufficient - but not necessary - conditions on separability.
