Perfect State Transfer: Beyond Nearest-Neighbor Couplings
Alastair Kay
In this paper we build on the ideas presented in previous works for perfectly transferring a quantum state between opposite ends of a spin chain using a fixed Hamiltonian. While al…

Error Correcting the Control Unit in Global Control Schemes
Alastair Kay
Recent studies of globally controlled structures have culminated in a theoretical demonstration that fault-tolerant quantum computation can be carried out on a one--dimensional cha…

Geometric Effects and Computation in Spin Networks
Alastair Kay, Marie Ericsson
When initially introduced, a Hamiltonian that realises perfect transfer of a quantum state was found to be analogous to an x-rotation of a large spin. In this paper we extend the a…
