Query: Experimental Demonstration of Quantum Lattice Gas Computation   We report an ensemble nuclear magnetic resonance (NMR) implementation of a
quantum lattice gas algorithm for the diffusion equation. The algorithm employs
an array of quantum information processors sharing classical information, a
novel architecture referred to as a type-II quantum computer. This concrete
implementation provides a test example from which to probe the strengths and
limitations of this new computation paradigm. The NMR experiment consists of
encoding a mass density onto an array of 16 two-qubit quantum information
processors and then following the computation through 7 time steps of the
algorithm. The results show good agreement with the analytic solution for
diffusive dynamics. We also describe numerical simulations of the NMR
implementation. The simulations aid in determining sources of experimental
errors, and they help define the limits of the implementation.
