    "abstract": "We derive bounds on the entanglement of formation of states of a 4xN\nbipartite system using two entanglement monotones constructed from operational\nseparability criteria. The bounds are used simultaneously as constraints on the\nentanglement of formation. One monotone is the negativity, which is based on\nthe Peres positive-partial-transpose criterion. For the other, we formulate a\nmonotone based on a separability criterion introduced by Breuer (H.-P. Breuer,\ne-print quant-ph/0605036).",
