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…

Perfect Transfer of Arbitrary States in Quantum Spin Networks
Matthias Christandl, Nilanjana Datta, Tony C. Dorlas +3
We propose a class of qubit networks that admit perfect state transfer of any two-dimensional quantum state in a fixed period of time. We further show that such networks can distri…
