    "abstract": "When initially introduced, a Hamiltonian that realises perfect transfer of a\nquantum state was found to be analogous to an x-rotation of a large spin. In\nthis paper we extend the analogy further to demonstrate geometric effects by\nperforming rotations on the spin. Such effects can be used to determine\nproperties of the chain, such as its length, in a robust manner. Alternatively,\nthey can form the basis of a spin network quantum computer. We demonstrate a\nuniversal set of gates in such a system by both dynamical and geometrical\nmeans.",
