    "abstract": "We propose a decoherence-free subspaces (DFS) scheme to realize scalable\nquantum computation with trapped ions. The spin-dependent Coulomb interaction\nis exploited, and the universal set of unconventional geometric quantum gates\nis achieved in encoded subspaces that are immune from decoherence by collective\ndephasing. The scalability of the scheme for the ion array system is\ndemonstrated, either by an adiabatic way of switching on and off the\ninteractions, or by a fast gate scheme with comprehensive DFS encoding and\nnoise decoupling techniques.",
