    "abstract": "Universal ion trap computation on Decoherence Free Subspaces (DFS) using only\ntwo qubit operations is presented. The DFS is constructed for the collective\ndephasing model. Encoded single and two-qubit logical operations are\nimplemented via the Sorensen-Molmer interaction. Alternation of the effective\nHamiltonians for two particular phase configurations of control fields\napproximates an anisotropic exchange interaction. This is universal over\nsuitable encodings of one logical qubit into three physical qubits which are\nalso DFS under collective decoherence.",
