Brokered Graph-state Quantum Computation

摘要

Using the graph state approach to quantum computation, one can avoid the need for complex array nanostructures in which quantum bits (qubits) interact directly. Instead one can employ we describe a robust coupling procedure, which we call Brokering, that is especially well suited to nanostructures bearing both nuclear and electron spins. We describe how this approach can be implemented with N-V centre materials.
