The Relation of Concurrence and Purity for Multi-Qubit of Pure States

Quantizing multi-qubit entanglement is important for quantum information processing communication. In this paper, we study the relations between concurrence and purity of multi-qubit of pure states through detail calculation. For the maximally entangled states, we find that the averaged purity reach...

Zusammenfassung:Quantizing multi-qubit entanglement is important for quantum information processing communication. In this paper, we study the relations between concurrence and purity of multi-qubit of pure states through detail calculation. For the maximally entangled states, we find that the averaged purity reaches its minimum; the concurrence reaches its maximum. Such results can be applied in quantizing multi-qubit entanglement.
