Abstract

In this paper, we introduce a category of one-parameter bipartite entanglement quantifiers, termed G_q-concurrence (q>1), and show rigorously that they satisfy all the axiomatic conditions of an entanglement measure and can be considered as a generalization of concurrence. In addition, we establish an analytic formula relating G_q-concurrence to concurrence for 1
