    "abstract": "We study the quantum computational power of a generic class of anisotropic\nsolid state Hamiltonians. A universal set of encoded logic operations are found\nwhich do away with difficult-to-implement single-qubit gates in a number of\nquantum computer proposals, e.g., quantum dots and donor atom spins with\nanisotropic exchange coupling, quantum Hall systems, and electrons floating on\nhelium.We show how to make the corresponding Hamiltonians universal by encoding\none qubit into two physical qubits, and by controlling nearest neighbor\ninteractions.",
