چکیده
We have introduced a new class of multipartite entangled mixed states with pure state de-compositions of generalized W states, similar to SC states having generalized GHZ states in the pure state decomposition. The entanglement and separability properties are studied according to PPT operations. Monogamy relations related to these states are also investigated .

für Mathematik in den Naturwissenschaften Leipzig Concurrence , Tangle and Fully Entangled Fraction
We show that although we can not distill a singlet from many pairs of bound entangled states, the concurrence and tangle of two entangled quantum states are always strictly larger than that of one, even both entangled quantum states are bound entangled. We present a relation between the concurrence and the fidelity of optimal teleportation. We also give new upper and lower bounds for concurrenc...
متن کاملfür Mathematik in den Naturwissenschaften Leipzig Gisin ’ s Theorem for Arbitrary Dimensional Multipartite States
We present a set of Bell inequalities which are sufficient and necessary for separability of general pure multipartite quantum states in arbitrary dimensions. The relations between Bell inequalities and distillability are also studied. We show that any quantum states that violate one of these Bell inequalities are distillable.
