N2 - We compute the minimal energy cost forextracting entanglement from the groundstate of a bosonic or fermionic quadraticsystem. Specifically, we find the minimalenergy increase in the system resulting from replacing an entangled pair of modes, sharing entanglement entropy S, by a product state, and we show how to construct modes achieving this minimal energy cost. Thus, we obtain a protocol independent lower bound on the extraction of pure state entanglement from quadratic systems.
