Entanglement entropy in quantum fluids and gases

Quantum mechanics is responsible for the impending violation of Moore's law by placing a lower bound on the size of a solid state transistor. However, a new era of exponentially faster computation may be ushered in by harnessing its power through the use of quantum entanglement as a resource.  Some of the most intriguing and scalable proposals for constructing functionally entangled states that would 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 systems of itinerant bosons in the spatial continuum. We discuss how the experimentally measurable condensate fraction can be used to bound the entanglement between quantum particles, and present results for interacting bosons in one spatial dimension.
