A comparison of entanglement measures — •Jens Eisert¹ and Martin Plenio² — ¹Institut für Physik, Universität Potsdam, 14469 Potsdam, Germany — ²Blackett Laboratory, Imperial College, Prince Consort Road, London SW7 2BZ, U.K.

We compare the entanglement of formation with a measure defined as the modulus of the negative eigenvalue of the partial transpose. In particular, we investigate whether both measures give the same ordering of density operators with respect to the amount of entanglement.
