Some of the most intriguing and scalable proposals for constructing functionally entangled states that could form the qubits of a quantum computer employ ultracold atomic gases and Bose-Einstein condensates. In this talk, we introduce a novel computer simulation technique able to quantify and optimize entanglement in these systems.  We demonstrate its utility by studying interacting Bose gases in one spatial dimension where we uncover a logarithmic scaling of the entanglement entropy and confirm bounds on it related to the experimentally measurable condensate fraction.  The application of this method may yield the first quantitative measures of quantum entanglement in experimentally accessible ultracold atomic gases and high density quantum liquids.
