    "abstract": "Hilbert-Schmidt distance reduces to Euclidean distance in Bell decomposable\nstates. Based on this, entanglement of these states are obtained according to\nthe protocol proposed in Ref. [V. Vedral et al, Phys. Rev. Lett. 78, 2275\n(1995)] with Hilbert-Schmidt distance. It is shown that this measure is equal\nto the concurrence and thus can be used to generate entanglement of formation.\nWe also introduce a new measure of distance and show that under the action of\nrestricted LQCC operations, the associated measure of entanglement transforms\nin the same way as the concurrence transforms .",
