    "abstract": "We give an explicit tight lower bound for the entanglement of formation for\narbitrary bipartite mixed states by using the convex hull construction of a\ncertain function. This is achieved by revealing a novel connection among the\nentanglement of formation, the well-known Peres-Horodecki and realignment\ncriteria. The bound gives a quite simple and efficiently computable way to\nevaluate quantitatively the degree of entanglement for any bipartite quantum\nstate.",
