    "abstract": "We introduce a Gaussian version of the entanglement of formation adapted to\nbipartite Gaussian states by considering decompositions into pure Gaussian\nstates only. We show that this quantity is an entanglement monotone under\nGaussian operations and provide a simplified computation for states of\narbitrary many modes. For the case of one mode per site the remaining\nvariational problem can be solved analytically. If the considered state is in\naddition symmetric with respect to interchanging the two modes, we prove\nadditivity of the considered entanglement measure. Moreover, in this case and\nconsidering only a single copy, our entanglement measure coincides with the\ntrue entanglement of formation.",
