    "abstract": "We show that trapped ions can be used to simulate a highly symmetrical\nHamiltonian with eingenstates naturally protected against local sources of\ndecoherence. This Hamiltonian involves long range coupling between particles\nand provides a more efficient protection than nearest neighbor models discussed\nin previous works. Our results open the perspective of experimentally realizing\nin controlled atomic systems, complex entangled states with decoherence times\nup to nine orders of magnitude longer than isolated quantum systems.",
