Concurrence-Based Entanglement Measure for Werner States

Kai Chen, Sergio Albeverio and Shao-Ming Fei

Abstract

We give explicit expressions for entanglement measures of Werner states in arbitrary dimensions in terms of concurrence and tangle. We show that an optimal ensemble decomposition for a joint density matrix of a Werner state can achieve the minimum average concurrence and tangle simultaneously. Furthermore, the same decomposition also attains entanglement of formation for Werner states.
