We present a scheme for quantum communication that involves the distribution of a topological cluster state throughout a quantum network. Photon loss and other errors are suppressed by optical multiplexing and entanglement purification. We discuss implementation of an individual node composed of Erbium spins (single atom or ensemble) coupled via flux qubits to a superconducting resonator, allowing for deterministic local gates, stable quantum memories, and emission of photons in the telecom regime.
