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. We will describe error models for this new architecture. With the remaining time we will present a neutral atom optical lattice as one example of the application of this architecture.
