Quantum Computing with Bose-Einstein Condensates and Effective Nonlinearities

Tom G. Wong
University of California, San Diego

physicsAlthough quantum mechanics is linear, there are nevertheless quantum systems with multiple interacting particles in which the effective evolution of a single particle is governed by a nonlinear Schrödinger equation. Bose-Einstein condensates, for example, can be described by the Gross-Pitaevskii Equation under certain conditions, which has a term proportional to the cube of the wavefunction. In this talk, I show that such realistic nonlinearities confer a significant, but not unreasonable, computational advantage when searching a "database."
