Abstract

Many protocols for quantum information processing use a control sequence or circuit of interactions between qubits and control fields wherein arbitrary qubits can be made to interact with one another. The primary problem with many "physically scalable" architectures is that the qubits are restricted to nearest neighbor interactions and quantum wires between distant qubits do not exist. Because of errors, nearest neighbor interactions often present difficulty with scalability. In this paper we describe a generalized quantum architecture that provides efficient nonlocal operations for such a system. We describe a protocol that efficiently performs nonlocal gates between elements of separated static logical qubits using a bus of dynamic qubits that can be used as a refreshable entanglement resource.
