  We propose an experimental scheme to simulate the transverse field Ising
model with cold atoms trapped in one-dimensional optical lattice. Majorana
fermions are created at the ends of the optical lattice segment in topological
phase. By controlling the addressing lasers, one can move, fuse and braid them.
We also show that the non-Abelian braiding statistics of Majorana fermions can
be demonstrated unambiguously through the construction of two braiding
operations and distinguishing the resulting two output orthogonal collective
spin states. A nice feature of the scheme is that the strong fluorescence
provided by the collective spin state can be readily detected in experiment.
