Lower Bounds of Entanglement Quantifiers Based On Entanglement Witnesses

To quantify the entanglement of bipartite systems in terms of some entanglement measure is a challenging problem in general, and it is much worse when the information about the system is less. In this manuscript, based on two classes of entanglement criteria, we present a method to obtain the lower bounds of the entanglement measures, concurrence, entanglement of formation, and geometrical entanglement measure.
