(Colorado School of Mines)
We describe a fully connected spin network model for quantum information processing applications. This scalable network in the case of spin 1/2 has recently been realized in the laboratory, using Josephson phase qubits, and other solid-state implementations are likely. We have recently jointly developed a rigorous protocol for producing the important maximally entangled generalized GHZ states for this implementation . (GHZ states generalize the well known Bell states for two qubits.) An exact solution for the eigenstructure of a certain subspace of partial uniform superpositions enables the protocol to be detailed for an arbitrary number of qubits. An overview of this work and a short description of other quantum information processing applications of the spin network will be given. Joint work with Andrei Galiautdinov and Ron Deiotte.  A.
