Entanglement of Formation and Concurrence for Mixed States

Xiu-Hong Gao, Sergio Albeverio, Kai Chen, Shao-Ming Fei and Xianqing Li-Jost

Abstract

We review some results on analytical computations of the measures for quantum entanglement: entanglement of formation and concurrence. We introduce some estimations of the lower bounds for the entanglement of formation in bipartite mixed states, and of lower bounds for the concurrence in bipartite and tripartite systems. The results on lower bounds for the concurrence are also generalized to arbitrary multipartite systems.
